Hewlett-Packard Company or HP (styled as 【hp】) is an American multinational information technology corporation headquartered in Palo Alto, California, United States. It provides hardware, software and services to consumers, small- and medium-sized businesses (SMBs) and large enterprises, including customers in the government, health and education sectors.

The company was founded in a one-car garage in Palo Alto by William "Bill" Redington Hewlett, David "Dave" Packard, and Mike Limon, starting with a line of electronic test equipment. HP is the world's leading PC manufacturer and has been since 2007, fending off a challenge by Chinese manufacturer Lenovo, according to Gartner.[2] It specializes in developing and manufacturing computing, data storage, and networking hardware, designing software and delivering services. Major product lines include personal computing devices, enterprise and industry standard servers, related storage devices, networking products, software and a diverse range of printers and other imaging products. HP markets its products to households, small- to medium-sized businesses and enterprises directly as well as via online distribution, consumer-electronics and office-supply retailers, software partners and major technology vendors. HP also has services and consulting business around its products and partner products. In 2014 it was the world's second-largest personal computer vendor by unit sales after Lenovo.[3]

Hewlett-Packard company events have included the spin-off of its electronic and bio-analytical measurement instruments part of its business as Agilent Technologies in 1999, its merger with Compaq in 2002, the sponsor of Mission: Space in 2003, and the acquisition of EDS in 2008, which led to combined revenues of $118.4 billion in 2008 and a Fortune 500 ranking of 9 in 2009. In November 2009, HP announced the acquisition of 3Com,[4] with the deal closing on April 12, 2010.[5] On April 28, 2010, HP announced the buyout of Palm, Inc. for $1.2 billion.[6] On September 2, 2010, HP won its bidding war for 3PAR with a $33 a share offer ($2.07 billion), which Dell declined to match.[7]

On October 6, 2014, Hewlett-Packard announced plans to split the PC and printers business from its enterprise products and services business. The split is expected to close by October 2015 and will result in two publicly traded companies: Hewlett-Packard Enterprise and HP, Inc.[8]

History

Founding


The garage in Palo Alto where Hewlett and Packard began their company

Bill Hewlett [9] and Dave Packard graduated with degrees in electrical engineering from Stanford University in 1935. The company originated in a garage in nearby Palo Alto during a fellowship they had with a past professor, Frederick Terman at Stanford during the Great Depression. Terman was considered a mentor to them in forming Hewlett-Packard.[10] In 1939, Packard and Hewlett established Hewlett-Packard (HP) in Packard's garage with an initial capital investment of US$538.[11] Hewlett and Packard tossed a coin to decide whether the company they founded would be called Hewlett-Packard or Packard-Hewlett.[12] HP incorporated on August 18, 1947, and went public on November 6, 1957.

Of the many projects they worked on, their very first financially successful product was a precision audio oscillator, the Model HP200A. Their innovation was the use of a small incandescent light bulb (known as a "pilot light") as a temperature dependent resistor in a critical portion of the circuit, the negative feedback loop which stabilized the amplitude of the output sinusoidal waveform. This allowed them to sell the Model 200A for $54.40 when competitors were selling less stable oscillators for over $200. The Model 200 series of generators continued until at least 1972 as the 200AB, still tube-based but improved in design through the years.

One of the company's earliest customers was Walt Disney Productions which bought eight Model 200B oscillators (at $71.50 each) for use in certifying the Fantasound surround sound systems installed in theaters for the movie Fantasia.

Early years

They worked on counter-radar technology and artillery shell fuses during World War II, which allowed Packard (but not Hewlett) to be exempt from the draft.[13]

1960s

HP is recognized as the symbolic founder of Silicon Valley, although it did not actively investigate semiconductor devices until a few years after the "traitorous eight" had abandoned William Shockley to create Fairchild Semiconductor in 1957. Hewlett-Packard's HP Associates division, established around 1960, developed semiconductor devices primarily for internal use. Instruments and calculators were some of the products using these devices.

HP partnered in the 1960s with Sony and the Yokogawa Electric companies in Japan to develop several high-quality products. The products were not a huge success, as there were high costs in building HP-looking products in Japan. HP and Yokogawa formed a joint venture (Yokogawa-Hewlett-Packard) in 1963 to market HP products in Japan.[14] HP bought Yokogawa Electric's share of Hewlett-Packard Japan in 1999.[15]

HP spun off a small company, Dynac, to specialize in digital equipment. The name was picked so that the HP logo "hp" could be turned upside down to be a reverse reflect image of the logo "dy" of the new company. Eventually Dynac changed to Dymec, then was folded back into HP in 1959.[16] HP experimented with using Digital Equipment Corporation (DEC) minicomputers with its instruments, but after deciding that it would be easier to build another small design team than deal with DEC, HP entered the computer market in 1966 with the HP 2100 / HP 1000 series of minicomputers. These had a simple accumulator-based design, with registers arranged somewhat similarly to the Intel x86 architecture still used today. The series was produced for 20 years, in spite of several attempts to replace it, and was a forerunner of the HP 9800 and HP 250 series of desktop and business computers.

1970s

The HP 3000 was an advanced stack-based design for a business computing server, later redesigned with RISC technology. The HP 2640 series of smart and intelligent terminals introduced forms-based interfaces to ASCII terminals, and also introduced screen labeled function keys, now commonly used on gas pumps and bank ATMs. The HP 2640 series included one of the first bit mapped graphics displays that when combined with the HP 2100 21MX F-Series microcoded Scientific Instruction Set[17] enabled the first commercial WYSIWYG Presentation Program, BRUNO that later became the program HP-Draw on the HP 3000. Although scoffed at in the formative days of computing, HP would eventually surpass even IBM as the world's largest technology vendor, in terms of sales.[18]

"The new Hewlett-Packard 9100A personal computer is ready, willing, and able ... to relieve you of waiting to get on the big computer."

Although Programma 101 was the first commercial "desktop computer", HP is identified by Wired magazine as the producer of the world's first device to be called a personal computer, the Hewlett-Packard 9100A, introduced in 1968.[19] HP called it a desktop calculator, because, as Bill Hewlett said, "If we had called it a computer, it would have been rejected by our customers' computer gurus because it didn't look like an IBM. We therefore decided to call it a calculator, and all such nonsense disappeared." An engineering triumph at the time, the logic circuit was produced without any integrated circuits; the assembly of the CPU having been entirely executed in discrete components. With CRT display, magnetic-card storage, and printer, the price was around $5,000. The machine's keyboard was a cross between that of a scientific calculator and an adding machine. There was no alphabetic keyboard.

Steve Wozniak, co-founder of Apple, originally designed the Apple I computer while working at HP and offered it to them under their right of first refusal to his work, but they did not take it up as the company wanted to stay in scientific, business, and industrial markets.[citation needed]

The company earned global respect for a variety of products. They introduced the world's first handheld scientific electronic calculator in 1972 (the HP-35), the first handheld programmable in 1974 (the HP-65), the first alphanumeric, programmable, expandable in 1979 (the HP-41C), and the first symbolic and graphing calculator, the HP-28C. Like their scientific and business calculators, their oscilloscopes, logic analyzers, and other measurement instruments have a reputation for sturdiness and usability (the latter products are now part of spin-off Agilent's product line). The company's design philosophy in this period was summarized as "design for the guy at the next bench".[citation needed]

The 98x5 series of technical desktop computers started in 1975 with the 9815, and the cheaper 80 series, again of technical computers, started in 1979 with the 85.[20] These machines used a version of the BASIC programming language which was available immediately after they were switched on, and used a proprietary magnetic tape for storage. HP computers were similar in capabilities to the much later IBM Personal Computer, although the limitations of available technology forced prices to be high.[citation needed]

1980s

In 1984, HP introduced both inkjet and laser printers for the desktop. Along with its scanner product line, these have later been developed into successful multifunction products, the most significant being single-unit printer/scanner/copier/fax machines. The print mechanisms in HP's tremendously popular LaserJet line of laser printers depend almost entirely on Canon's components (print engines), which in turn use technology developed by Xerox. HP develops the hardware, firmware, and software that convert data into dots for the mechanism to print.[citation needed] HP transitioned from the HP3000 to the HP9000 series minicomputers with attached storage such as the HP 7935 hard drive holding 404 MiB.

On March 3, 1986, HP registered the HP.com domain name, making it the ninth Internet .com domain ever to be registered.

In 1987, the Palo Alto garage where Hewlett and Packard started their business was designated as a California State historical landmark.

1990s

In the 1990s, HP expanded their computer product line, which initially had been targeted at university, research, and business users, to reach consumers.

HP also grew through acquisitions, buying Apollo Computer in 1989 and Convex Computer in 1995.
Later in the decade, HP opened hpshopping.com as an independent subsidiary to sell online, direct to consumers; in 2005, the store was renamed "HP Home & Home Office Store."

From 1995 to 1998, Hewlett-Packard were sponsors of the English football team Tottenham Hotspur.
In 1999, all of the businesses not related to computers, storage, and imaging were spun off from HP to form Agilent Technologies. Agilent's spin-off was the largest initial public offering in the history of Silicon Valley.[21] The spin-off created an $8 billion company with about 30,000 employees, manufacturing scientific instruments, semiconductors, optical networking devices, and electronic test equipment for telecom and wireless R&D and production.

In July 1999, HP appointed Carly Fiorina as CEO, the first female CEO of a company in the Dow Jones Industrial Average. Fiorina served as CEO during the technology industry downturn of the early 2000s. During her tenure, the market value of HP halved and the company incurred heavy job losses.[22] The HP Board of Directors asked Fiorina to step down in 2005, and she resigned on February 9, 2005.

On September 3, 2001, HP announced that an agreement had been reached with Compaq to merge the two companies.[23] In May, 2002, after passing a shareholder vote, HP officially merged with Compaq. Prior to this, plans had been in place to consolidate the companies' product teams and product lines.[24]

In 1998, Compaq had already taken over Digital Equipment Corporation. HP therefore still offers support for the former Digital Equipment products PDP-11, VAX and AlphaServer.

The merger occurred after a proxy fight with Bill Hewlett's son Walter, who objected to the merger. Compaq itself had bought Tandem Computers in 1997 (which had been started by ex-HP employees), and Digital Equipment Corporation in 1998. Following this strategy, HP became a major player in desktops, laptops, and servers for many different markets. After the merger with Compaq, the new ticker symbol became "HPQ", a combination of the two previous symbols, "HWP" and "CPQ", to show the significance of the alliance and also key letters from the two companies Hewlett-Packard and Compaq (the latter company being famous for its "Q" logo on all of its products.)

In 2004, HP released the DV 1000 Series, including the HP Pavilion dv 1658 and 1040 two years later in May 2006, HP began its campaign, The Computer is Personal Again. The campaign was designed to bring back the fact that the PC is a personal product. The campaign utilized viral marketing, sophisticated visuals, and its own website (www.hp.com/personal). Some of the ads featured Pharrell, Petra Nemcova, Mark Burnett, Mark Cuban, Alicia Keys, Jay-Z, Gwen Stefani, and Shaun White.[citation needed]

On May 13, 2008, HP and Electronic Data Systems (EDS) announced[25] that they had signed a definitive agreement under which HP would purchase EDS. On June 30, HP announced[26] that the waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976 had expired. "The transaction still requires EDS stockholder approval and regulatory clearance from the European Commission and other non-U.S. jurisdictions and is subject to the satisfaction or waiver of the other closing conditions specified in the merger agreement." The agreement was finalized on August 26, 2008, and it was publicly announced that EDS would be re-branded "EDS an HP company." As of September 23, 2009, EDS is known as HP Enterprise Services.

On November 11, 2009, 3Com and Hewlett-Packard announced that Hewlett-Packard would be acquiring 3Com for $2.7 billion in cash.[27] The acquisition is one of the biggest in size among a series of takeovers and acquisitions by technology giants to push their way to become one-stop shops. Since the beginning of the financial crisis in 2007, tech giants have constantly felt the pressure to expand beyond their current market niches. Dell purchased Perot Systems recently to invade into the technology consulting business area previously dominated by IBM. Hewlett-Packard's latest move marked its incursion into enterprise networking gear market dominated by Cisco.

2010s

On April 28, 2010, Palm, Inc. and Hewlett-Packard announced that HP would be acquiring Palm for $1.2 billion in cash and debt,[28] In the months leading up to the buyout, it was rumored that Palm was going to be purchased by either HTC, Dell, RIM or HP. The addition of Palm handsets to the HP product line provided some overlap with the then current iPAQ mobile products but was thought to significantly increase HP's mobile presence as those devices had not been selling well. The addition of Palm brought to HP a library of valuable patents as well as the mobile operating platform known as webOS. On July 1, 2010, the acquisition of Palm was final.[29] The purchase of Palm, Inc.'s webOS began a big gamble – to build HP's own ecosystem.[30] On July 1, 2011, HP launched its first tablet named HP TouchPad, bringing webOS to tablet devices. On September 2, 2010, HP won its bidding war for 3PAR with a $33 a share offer ($2.07 billion) which Dell declined to match. Following HP's acquisition of Palm, it would phase out the Compaq brand.

On August 6, 2010, CEO Mark Hurd resigned amid controversy and CFO Cathie Lesjak assumed the role of interim CEO. Hurd had turned HP around and was widely regarded as one of Silicon Valley's star CEOs, but was accused of sexual harassment against a colleague. Although the allegations were deemed baseless, the investigation led to questions concerning between $1000 and $20000 of his private expenses and his lack of disclosure related to the friendship.[31][32] Some observers have argued that Hurd was innocent, but the board asked for his resignation to avoid negative PR.[33] Public analysis was divided between those who saw it as a commendable tough action by HP in handling expenses irregularities, and those who saw it as an ill-advised, hasty and expensive reaction, in ousting a remarkably capable leader who had turned the business around.[31][32][34] Shares of HP dropped by 8.4% in after-hours trading, hitting a 52-week low with $9 billion in market capitalization shaved off.[35] Larry Ellison publicly attacked HP's board for his ousting.[36]

On September 30, 2010, Léo Apotheker was named as HP's new CEO and President.[37] Apotheker's appointment sparked a strong reaction from Oracle chief executive Larry Ellison,[38] who complained that Apotheker had been in charge of SAP when one of its subsidiaries was systematically stealing software from Oracle. SAP accepted that its subsidiary, which has now closed, illegally accessed Oracle intellectual property.[39] Following Hurd's departure, HP was seen by the market as problematic, with margins falling and having failed to redirect and establish itself in major new markets such as cloud and mobile services.[citation needed] Apotheker's strategy was broadly to aim at disposing of hardware and moving into the more profitable software services sector. On August 18, 2011, HP announced that it would strategically exit the smartphone and tablet computer business, focusing on higher-margin "strategic priorities of Cloud, solutions and software with an emphasis on enterprise, commercial and government markets"[40] They also contemplated selling off their personal computer division or spinning it off into a separate company,[41] quitting the 'PC' business, while continuing to sell servers and other equipment to business customers, was a strategy already undertaken by IBM in 2005.[42]

HP's stock continued to drop, by about a further 40% (including 25% on one day, 19 August 2011), after the company abruptly announced a number of decisions: to discontinue its webOS device business (mobile phones and tablet computers), the intent to sell its personal computer division (at the time HP was the largest personal computer manufacturer in the world), and to acquire British big data software firm Autonomy for a 79% premium, seen externally as an "absurdly high" price[43] for a business with known concerns over its accounts.[44] Media analysts described HP's actions as a "botched strategy shift" and a "chaotic" attempt to rapidly reposition HP and enhance earnings that ultimately cost Apotheker his job.[43][45][46] The Autonomy acquisition had been objected to even by HP's own CFO.[47][48]:3–6

On September 22, 2011, the HP Board of Directors fired Apotheker as chief executive, effective immediately, and replaced him with fellow board member and former eBay chief Meg Whitman,[49] with Raymond J. Lane as executive chairman. Though Apotheker served barely ten months, he received over $13 million in compensation.[50] HP lost more than $30 billion in market capitalization during his tenure. Weeks later, HP announced that a review had concluded their PC division was too integrated and critical to business operations, and the company reaffirmed their commitment to the Personal Systems Group.[51] A year later in November 2012 wrote-down almost $9 billion related to the Autonomy acquisition (see below: Takeover of Autonomy), which became the subject of intense litigation as HP accused Autonomy's previous management of fraudulently exaggerating Autonomy's financial position and called in law enforcement and regulators in both countries, and Autonomy's previous management accused HP of "textbook" obfuscation and finger pointing to protect HP's executives from criticism and conceal HP culpability, their prior knowledge of Autonomy's financial position, and gross mismanagement of Autonomy after acquisition.[48]:6

On March 21, 2012, HP said its printing and PC divisions would become one unit headed by Todd Bradley from the PC division. Printing chief Vyomesh Joshi is leaving the company.[52]

On May 23, 2012, HP announced plans to lay off approximately 27,000 employees, after posting a profit decline of 31% in the second quarter of 2012.[53] The profit decline is on account of the growing popularity of smart phones, tablets, and other mobile devices, that has slowed the sale of personal computers.[54]

On May 30, 2012, HP unveiled its first net zero energy data center. HP data center plans to use solar energy and other renewable sources instead of traditional power grids.[55]

On July 10, 2012, HP's Server Monitoring Software was discovered to have a previously unknown security vulnerability.[56] A security warning was given to customers about two vulnerabilities, and a patch released.[57] One month later HP's official site of training center was hacked and defaced by a Pakistani hacker known to as 'Hitcher' to demonstrate a web vulnerability.[58]

On September 10, 2012, HP revised their restructuring figures; they are now cutting 29,000 jobs. HP had already cut 3,800 jobs – around 7 percent of the revised 29,000 figure – as of July 2012.[59]

On December 31, 2013, HP revised the amount of jobs cut from 29,000 to 34,000 up to October 2014. The current amount of jobs cut until the end of 2013 was 24,600.[60][61][62] At the end of 2013 the company had 317,500 employees. On May 22, 2014 HP announced it would cut a further 11,000 to 16,000 jobs, in addition to the 34,000 announced in 2013. "We are gradually shaping HP into a more nimble, lower-cost, more customer and partner-centric company that can successfully compete across a rapidly changing IT landscape," CEO Meg Whitman said at the time.[63]

In June 2014, during the HP Discover customer event in Las Vegas, Meg Whitman and Martin Fink announced a project for a radically new computer architecture called The Machine. Based on memristors and silicon photonics, The Machine is supposed to come in commercialization before the end of the decade, meanwhile representing 75% of the research activity in HP Labs.[64]

On October 6, 2014, Hewlett Packard announced it was planning to break into two separate companies, separating its personal-computer and printer businesses from its technology services. The split, which was first reported by The Wall Street Journal and confirmed by other media, will result in two publicly traded companies: Hewlett-Packard Enterprise and HP, Inc. Meg Whitman will serve as chairman of HP, Inc. and CEO of Hewlett-Packard Enterprise, Patricia Russo will be chairman of the enterprise business, and Dion Weisler will be CEO of HP, Inc. The split is expected to be completed by the end of fiscal year 2015, in October 2015.[65][66][67]

On October 29, 2014, Hewlett-Packard announced their new Sprout personal computer.[68]

Facilities

HP's global operations are directed from its headquarters in Palo Alto, California, USA. Its U.S. operations are directed from its facility in unincorporated Harris County, Texas, near Houston. Its Latin America offices in unincorporated Miami-Dade County, Florida, U.S., near Miami and in Medellín, Colombia. Its Europe offices are in Meyrin, Switzerland, near Geneva, but it has also a research center in the Paris-Saclay cluster, 20 km in the south of Paris, France. Its Asia-Pacific offices are in Singapore.[69][70][71][72][71][73][74]

It also has large operations in Austin, Texas, Boise, Idaho; Roseville, California; Fort Collins, Colorado; Vancouver, Washington; San Diego; Tulsa, Oklahoma; and Plano, Texas (the former headquarters of EDS, which HP acquired). In the UK, HP is based at a large site in Bracknell, Berkshire with offices in various UK locations, including a landmark office tower in London, 88 Wood Street. Its recent acquisition of 3Com will expand its employee base to Marlborough, Massachusetts.[75] The company also has a large workforce and numerous offices at Bangalore, India, to address their back end and IT operations. MphasiS, which is headquartered at Bangalore, also enabled HP to increase their footprint in the city as it was a subsidiary of EDS which the company acquired.

Products and organizational structure

HP produces lines of printers, scanners, digital cameras, calculators, PDAs, servers, workstation computers, and computers for home and small-business use; many of the computers came from the 2002 merger with Compaq. HP as of 2001 promotes itself as supplying not just hardware and software, but also a full range of services to design, implement, and support IT infrastructure.
HP's Imaging and Printing Group (IPG) is "the leading imaging and printing systems provider in the world for printer hardware, printing supplies and scanning devices, providing solutions across customer segments from individual consumers to small and medium businesses to large enterprises".[76] Products and technology associated with IPG include:
On December 23, 2008, HP released iPrint Photo for iPhone, a free downloadable software application that allows the printing of 4" x 6" photos.[77]

HP's Personal Systems Group (PSG) claims to be "one of the leading vendors of personal computers ("PCs") in the world based on unit volume shipped and annual revenue."[76] PSG deals with:
  • business PCs and accessories
  • consumer PCs and accessories, (e.g., HP Pavilion, Compaq Presario, VoodooPC)
  • handheld computing (e.g., iPAQ Pocket PC)
  • digital "connected" entertainment (e.g., HP MediaSmart TVs, HP MediaSmart Servers, HP MediaVaults, DVD+RW drives)
HP resold the Apple iPod until November 2005.[76]

HP Enterprise Business (EB) incorporates HP Technology Services, Enterprise Services (an amalgamation of the former EDS, and what was known as HP Services), HP Enterprise Security Services oversees professional services such as network security, information security and information assurance/ compliancy, HP Software Division, and Enterprise Servers, Storage and Networking Group (ESSN). The Enterprise Servers, Storage and Networking Group (ESSN) oversees "back end" products like storage and servers. HP Networking (former ProCurve) is responsible for the NW family of products. They are a business unit of ESSN.

HP Software Division is the company's enterprise software unit. For years,[when?] HP has produced and marketed its brand of enterprise-management software, HP OpenView. From September 2005 HP purchased several software companies as part of a publicized, deliberate strategy to augment its software offerings for large business customers.[78] HP Software sells several categories of software, including:
HP Software also provides software as a service (SaaS), cloud computing solutions, and software services, including consulting, education, professional services, and support.

HP's Office of Strategy and Technology[79] has four main functions:
  1. steering the company's $3.6 billion research and development investment
  2. fostering the development of the company's global technical community
  3. leading the company's strategy and corporate development efforts,[80]
  4. performing worldwide corporate marketing activities
Under the Office of Strategy and Technology comes HP Labs, the research arm of HP. Founded in 1966, HP Labs aims to deliver new technologies and to create business opportunities that go beyond HP's current strategies. Examples of recent HP Labs technology includes the Memory spot chip of 2006. HP IdeaLab further provides a web forum on early-state innovations to encourage open feedback from consumers and the development community.[81]

HP also offers managed services by which they provide complete IT-support solutions for other companies and organizations. Some examples of these include:
  • offering "Professional Support" and desktop "Premier Support" for Microsoft in the EMEA marketplace. This is done from the Leixlip campus near Dublin, Sofia and Israel. Support is offered on the line of Microsoft operation systems, Exchange, Sharepoint and some office-applications.[82]
  • outsourced services for companies like Bank of Ireland, some UK banks, the U.S. defense forces.

Culture

The founders, known to friends and employees alike as Bill and Dave, developed a unique management style that came to be known as "The HP Way". In Bill's words, the HP Way is "a core ideology ... which includes a deep respect for the individual, a dedication to affordable quality and reliability, a commitment to community responsibility, and a view that the company exists to make technical contributions for the advancement and welfare of humanity."[83] The following are the tenets of The HP Way:[84]
  1. We have trust and respect for individuals.
  2. We focus on a high level of achievement and contribution.
  3. We conduct our business with uncompromising integrity.
  4. We achieve our common objectives through teamwork.
  5. We encourage flexibility and innovation.

Corporate social responsibility

In July 2007, the company announced that it had met its target, set in 2004, to recycle one billion pounds of electronics, toner and ink cartridges.[85] It has set a new goal of recycling a further two billion pounds of hardware by the end of 2010. In 2006, the company recovered 187 million pounds of electronics, 73 percent more than its closest competitor.[86]

In 2008, HP released its supply chain emissions data — an industry first.[87]

In September 2009, Newsweek ranked HP No. 1 on its 2009 Green Rankings of America's 500 largest corporations.[88] According to environmentalleader.com, "Hewlett-Packard earned its number one position due to its greenhouse gas (GHG) emission reduction programs, and was the first major IT company to report GHG emissions associated with its supply chain, according to the ranking. In addition, HP has made an effort to remove toxic substances from its products, though Greenpeace has targeted the company for not doing better."[89]

HP took the top spot on Corporate Responsibility Magazine '​s 100 Best Corporate Citizens List for 2010.[90] The list is cited by PR Week as one of America's most important business rankings. HP beat out other Russell 1000 Index companies because of its leadership in seven categories including environment, climate changes and corporate philanthropy. In 2009, HP was ranked fifth.[91]

Fortune magazine named HP one of the World's Most Admired Companies in 2010, placing it No. 2 in the computer industry and No. 32 overall in its list of the top 50. This year in the computer industry HP was ranked No. 1 in social responsibility, long-term investment, global competitiveness, and use of corporate assets.[92]

In May 2011, HP released a Global Responsibility report covering accomplishments during 2010.[93] The report, the company's tenth, provides a comprehensive view of HP's global citizenship programs, performance, and goals and describes how HP uses its technology, influence, and expertise to make a positive impact on the world. The company's 2009 report won best corporate responsibility report of the year.[94] The 2009 reports claims HP decreased its total energy use by 9 percent compared with 2008. HP recovered a total of 118,000 tonnes of electronic products and supplies for recycling in 2009, including 61 million print cartridges.[95]

In an April 2010 San Francisco Chronicle article, HP was one of 12 companies commended for "designing products to be safe from the start, following the principles of green chemistry." The commendations came from Environment California, an environmental advocacy group, who praised select companies in the Golden State and the Bay Area for their efforts to keep our planet clean and green.[96]

In May 2010, HP was named one of the World's Most Ethical Companies by Ethisphere Institute. This is the second year in a row HP has made the list. Ethisphere reviewed, researched and analyzed thousands of nominations in more than 100 countries and 35 industries to create the 2010 list. HP was one of only 100 companies to earn the distinction of top winner and was the only computer hardware vendor to be recognized. Ethisphere honors firms that promote ethical business standards and practices by going beyond legal minimums, introducing innovative ideas that benefit the public.[97]

HP is listed in Greenpeace's Guide to Greener Electronics that ranks electronics manufacturers according to their policies on sustainability, energy and climate and green products. In November 2011, HP secured the 1st place (out of 15) in this ranking (climbing up 3 places) with an increased score of 5.9 (up from 5.5). It scored most points on the new Sustainable Operations criteria, having the best program for measuring and reducing emissions of greenhouse gases from its suppliers and scoring maximum points for its thorough paper procurement policy.[98] In the November 2012 report, HP was ranked second, with a score of 5.7.[99]

HP does especially well for its disclosure of externally verified greenhouse gas emissions and its setting of targets for reducing them.[100] However, Greenpeace reports that HP risks a penalty point in future editions due to the fact that it is a member of trade associations that have commented against energy efficiency standards.[98]

HP has earned recognition of its work in the area of data privacy and security.[101] In 2010 the company ranked No. 4 in the Ponemon Institute's annual study of the most trusted companies for privacy.[102] Since 2006, HP has worked directly with the U.S. Congress, the Federal Trade Commission (FTC), and the Department of Commerce to establish a new strategy for federal legislation.[103] HP played a key role in work toward the December 2010 FTC report "Protecting Consumer Privacy in an Era of Rapid Change."[104]

After winning nine straight annual "Most Respected Company in China" awards from the Economic Observer and Peking University, HP China has added the "10 Year Contribution" award to its list of accolades. The award aims to identify companies doing business in China with outstanding and sustained performance in business operations, development and corporate social responsibility.[105]

In its 2012 rankings of consumer electronics companies on progress relating to conflict minerals, the Enough Project rated HP second out of 24 companies, calling it a "Pioneer of progress".[106]

Brand


A Hewlett-Packard sponsored Porsche 997 GT3 Cup

The company sponsored the HP Pavilion at San Jose (now SAP Center at San Jose), home to the NHL's San Jose Sharks.

According to a BusinessWeek Study, HP was the world's 11th most valuable brand as of 2009.[107]
HP has many sponsorships. One well known sponsorship is of Walt Disney World's Epcot Park's Mission: SPACE.[108] From 1995 to 1999, and again from 2013, HP has been the shirt sponsor of [109] Premier League club Tottenham Hotspur F.C.[citation needed] From 1997 to 1999 they were sponsors of Australian Football League club North Melbourne Football Club.[citation needed] They also sponsored the BMW Williams Formula 1 team until 2005 (a sponsorship formerly held by Compaq), and as of 2010 sponsor Renault F1.[citation needed] Hewlett-Packard also had the naming rights arrangement for the HP Pavilion at San Jose, home of the San Jose Sharks NHL hockey team until 2013, in which the arena's naming rights were acquired by SAP AG, renaming the arena to the SAP Center at San Jose.[110]

After the acquisition of Compaq in 2002, HP has maintained the "Compaq Presario" brand on low-end home desktops and laptops, the "HP Compaq" brand on business desktops and laptops, and the "HP ProLiant" brand on Intel-architecture servers. (The "HP Pavilion" brand is used on home entertainment laptops and all home desktops.)[111]

Tandem's "NonStop" servers are now branded as "HP Integrity NonStop".[112]

HP DISCOVER customer event

In 2011, HP Enterprise Business, along with participating independent user groups, combined its annual HP Software Universe, HP Technology Forum and HP Technology@Work into a single event, HP DISCOVER.[113] There are two HP Discover events annually, one for the Americas and one for Europe, Middle East and Africa (EMEA). HP DISCOVER 2011 Americas took place June 6–10, in Las Vegas at the Venetian/Palazzo.[114] The company demonstrated the webOS TouchPad, introduced July 1, 2011.[30][115]

The HP DISCOVER 2011 event in EMEA took place in Vienna, Austria, on November 29 through December 1, 2011.[116]

Controversies

Restatement

In March 2003, HP restated its first-quarter cash flow from operations, reducing it 18 percent because of an accounting error. Actual cash flow from operations was $647 million, not $791 million as reported earlier. HP shifted $144 million to net cash used in investing activities.[117]

Spying scandal

On September 5, 2006, Shawn Cabalfin and David O'Neil of Newsweek wrote that HP's general counsel, at the behest of chairwoman Patricia Dunn, contracted a team of independent security experts to investigate board members and several journalists in order to identify the source of an information leak.[118] In turn, those security experts recruited private investigators who used a spying technique known as pretexting.[119] The pretexting involved investigators impersonating HP board members and nine journalists (including reporters for CNET, the New York Times and the Wall Street Journal) in order to obtain their phone records. The information leaked related to HP's long-term strategy and was published as part of a CNET article[120] in January 2006. Most HP employees accused of criminal acts have since been acquitted.[121]

Hardware

In November 2007, Hewlett-Packard released a BIOS update covering a wide range of laptops with the intent to speed up the computer fan as well as have it run constantly, whether the computer was on or off.[122] The reason was to prevent the overheating of defective NVIDIA graphics processing units (GPUs) that had been shipped to many of the original equipment manufacturers, including Hewlett-Packard, Dell, and Apple.[123] The defect concerned the new packaging material used by NVIDIA from 2007 onwards in joining the graphics chip onto the motherboard, which did not perform well under thermal cycling and was prone to develop stress cracks – effectively severing the connection between the GPU and the motherboard, leading to a blank screen.[124] In July 2008, HP issued an extension to the initial one-year warranty to replace the motherboards of selected models.[125] However this option was not extended to all models with the defective NVIDIA chipsets despite research showing that these computers were also affected by the fault.[126] Furthermore the replacement of the motherboard was a temporary fix, since the fault was inherent in all units of the affected models from the point of manufacture, including the replacement motherboards offered by HP as a free 'repair'.[127][128] Since this point, several websites have been documenting the issue, most notably www.hplies.com, nvidiasettlement.com at the Wayback Machine (archived October 1, 2010), a forum dedicated to what they refer to as Hewlett-Packard's "multi-million dollar cover up" of the issue, and www.nvidiadefect.com [2], which details the specifics of the fault and offers advice to the owners of affected computers. There have been several small-claims lawsuits filed in several states, as well as suits filed in other countries. Hewlett-Packard also faced a class-action lawsuit in 2009 over its i7 processor computers. The complainants stated that their systems locked up within 30 minutes of powering on, consistently. Even after being replaced with newer i7 systems, the lockups continued.[129]

Lawsuit against Oracle

On June 15, 2011, HP filed a lawsuit in California Superior Court in Santa Clara, claiming that Oracle Corporation had breached an agreement to support the Itanium microprocessor used in HP's high-end enterprise servers.[130] On June 15, 2011, HP sent a "formal legal demand" letter to Oracle in an attempt to force the world's No. 3 software maker to reverse its decision to discontinue software development on Intel Itanium microprocessor.[131]

On August 1, 2012, HP released the following statement after winning the court ruling in Itanium Litigation:

The Court ordered and declared as follows:
  1. In this action for declaratory relief, the Court finds in favor of HP and against Oracle on both the breach of contract and promissory estoppel causes of action brought by HP.
  2. The Settlement and Release Agreement entered into by HP, Oracle and Mark Hurd on September 20, 2010, requires Oracle to continue to offer its product suite on HP's Itanium-based server platforms and does not confer on Oracle the discretion to decide whether to do so or not.
  3. The terms "product suite" means Oracle software products that were offered on HP's Itanium-based servers at the time Oracle signed the September 20, 2010 Settlement and Release Agreement, including any new releases, versions or updates of those products.
  4. Oracle's obligation to continue to offer its products on HP's Itanium-based server platforms lasts until such time as HP discontinues the sales of its Itanium-based servers.
  5. Oracle is required to port its products to HP's Itanium-based servers without charge to HP.

Takeover of Autonomy[edit]

In November 2012, HP recorded a writedown of around $8.8 billion related to its acquisition a year earlier of the UK based Autonomy Corporation PLC. HP accused Autonomy of deliberately inflating the value of the company prior to its takeover. The former management team of Autonomy flatly rejected the charge.
Autonomy specialized in analysis of large scale unstructured "big data", and by 2010 also the UK's largest and most successful[45] software business. It maintained an aggressively entrepreneurial marketing approach, and controls described as a "rod of iron", which was said to include zero tolerance and firing the weakest 5% of its sales force each quarter, while cosetting the best sales staff "like rock stars".[47]

At the time, HP had fired its previous CEO for expenses irregularities a year ago, and appointed Léo Apotheker as CEO and President. HP was seen as problematic by the market, with margins falling and having failed to redirect and establish itself in major new markets such as cloud and mobile services. Apotheker's strategy was to aim at disposing of hardware and moving into the more profitable software services sector.

As part of this strategy, Autonomy was acquired by HP in October 2011. HP paid $10.3 billion for 87.3% of the shares, valuing Autonomy at around $11.7 billion (£7.4 billion) overall, a premium of around 79% over market price. The deal was widely criticized as "absurdly high", a "botched strategy shift" and a "chaotic" attempt to rapidly reposition HP and enhance earnings,[43][45][46] and had been objected to even by HP's own CFO.[47][48]:3–6 Within a year, Apotheker himself had been fired, major culture clashes became apparent and HP had written off $8.8 billion of Autonomy's value.[47]

HP claim this resulted from "accounting improprieties, misrepresentations and disclosure failures" by the previous management, who in turn accuse HP of a "textbook example of defensive stalling[48]:6 to conceal evidence of its own prior knowledge and gross mismanagement and undermining of the company, noting public awareness since 2009 of its financial reporting issues[48]:3 and that even HP's CFO disagreed with the price paid.[47][48]:3–6 External observers generally state that only a small part of the write-off appears to be due to accounting mis-statements, and that HP had overpaid for businesses previously.[47][132]

The Serious Fraud Office (United Kingdom), and the U.S. Securities and Exchange Commission joined the FBI in investigating the potential anomalies. HP incurred much damage with its stock falling to decades' low.[133][134][135] Three lawsuits were brought by shareholders against HP, for the fall in value of HP shares. In August 2014 a United States district court judge threw out a proposed settlement, which Autonomy's previous management had argued would be collusive and intended to divert scrutiny of HP's own responsibility and knowledge, by essentially engaging the plaintiff's attorneys from the existing cases and redirecting them against the previous Autonomy vendors and management, for a fee of up to $48 million, with plaintiffs agreeing to end any claims against HP's management and similarly redirect those claims against the previous Autonomy vendors and management.[136][137] In January 2015 the SFO closed its investigation as the likelihood of a successful prosecution was low. [138] The dispute is still being litigated in the US, and is being investigated by the UK and Ireland Financial Reporting Council.

Bribery

On April 9, 2014, an administrative proceeding before Securities and Exchange Commission was settled by HP consenting to an order acknowledging that HP had violated the Foreign Corrupt Practices Act (FCPA) when HP subsidiaries in Russia, Poland, and Mexico made improper payments to government officials to obtain or retain lucrative public contracts.[139]

The SEC's order finds that HP's subsidiary in Russia paid more than $2 million through agents and various shell companies to a Russian government official to retain a multi-million dollar contract with the federal prosecutor's office. In Poland, HP's subsidiary provided gifts and cash bribes worth more than $600,000 to a Polish government official to obtain contracts with the national police agency. And as part of its bid to win a software sale to Mexico's state-owned petroleum company, HP's subsidiary in Mexico paid more than $1 million in inflated commissions to a consultant with close ties to company officials, and money was funneled to one of those officials. HP agreed to pay $108 million to settle the SEC charges and a parallel criminal case.[140][141][142]

Divestment from HP regarding involvement in Israeli occupation and blockade of Palestinian territories

On June 20, 2014, the Presbyterian Church (U.S.A.) voted to divest from Hewlett-Packard and two other American companies, Caterpillar and Motorola Solutions.[143][144][145][146]

The advisory opinion of the Presbyterian Peace Fellowship, which recommended divestment, cited HP's involvement in assisting Israel in maintaining the occupation of the Palestinian West Bank and human rights abuses of the Palestinians in the West Bank and the Gaza strip through its hardware and information technology support to the Israeli military and settlements.[147]

A near-Earth object (NEO) is a Solar System object whose orbit brings it into proximity with Earth. All NEOs have a closest approach to the Sun (perihelion) of less than 1.3 AU.[2] They include more than ten thousand near-Earth asteroids (NEAs), near-Earth comets, a number of solar-orbiting spacecraft, and meteoroids large enough to be tracked in space before striking the Earth. It is now widely accepted that collisions in the past have had a significant role in shaping the geological and biological history of the planet.[3] NEOs have become of increased interest since the 1980s because of increased awareness of the potential danger some of the asteroids or comets pose to Earth, and active mitigations are being researched.[4]

Those NEOs that are asteroids (NEA) have orbits that lie partly between 0.983 and 1.3 astronomical units away from the Sun.[5] When an NEA is detected it is submitted to the IAU's Minor Planet Center (located at the Harvard–Smithsonian Center for Astrophysics) for cataloging. Some near-Earth asteroids' orbits intersect that of Earth's so they pose a collision danger.[6] The United States, European Union, and other nations are currently scanning for NEOs[7] in an effort called Spaceguard.

In the United States, NASA has a congressional mandate to catalogue all NEOs that are at least 1 kilometer wide, as the impact of such an object would be catastrophic. As of February 2015, there have been 867 near-Earth asteroids larger than 1 km discovered, of which 153 are potentially hazardous asteroids (PHAs).[8] It was estimated in 2006 that 20% of the mandated objects have not yet been found.[7] As a result of NEOWISE in 2011, it is estimated that 93% of the NEAs larger than 1 km have been found and that only about 70 remain to be discovered.[9] Our inventory is much less complete for smaller objects, which still have potential for large scale damage.

Potentially hazardous objects (PHOs) are currently defined based on parameters that measure the object's potential to make threatening close approaches to the Earth.[10] Mostly objects with an Earth minimum orbit intersection distance (MOID) of 0.05 AU or less and an absolute magnitude (H) of 22.0 or brighter (a rough indicator of large size) are considered PHOs. Objects that cannot approach closer to the Earth (i.e. MOID) than 0.05 AU (7,500,000 km; 4,600,000 mi), or are smaller than about 150 m (500 ft) in diameter (i.e. H = 22.0 with assumed albedo of 13%), are not considered PHOs.[2] The NASA Near Earth Object Catalog also includes the approach distances of asteroids and comets measured in lunar distances,[11] and this usage has become a common unit of measure used by the news media in discussing these objects.

Some NEOs are of high interest because they can be physically explored with lower mission velocity even than the Moon, due to their combination of low velocity with respect to Earth (ΔV) and small gravity, so they may present interesting scientific opportunities both for direct geochemical and astronomical investigation, and as potentially economical sources of extraterrestrial materials for human exploitation.[12] This makes them an attractive target for exploration.[13] As of 2012, three near-Earth objects have been visited by spacecraft: 433 Eros, by NASA's Near Earth Asteroid Rendezvous probe,[14] 25143 Itokawa, by the JAXA Hayabusa mission,[15] and 4179 Toutatis, by CNSA's Chang'e 2 spacecraft.[4][16]

History of human awareness of NEOs


Asteroid Toutatis from Paranal.

Human perception of near-Earth objects as benign objects of fascination or killer objects with high risk to human society have ebbed and flowed in the short period of human history that NEOS have been scientifically observed.[17]

Risk


Asteroid 4179 Toutatis is a potentially hazardous object that has passed within 2.3 lunar distances.

More recently, a typical frame of reference for looking at NEOs has been through the scientific concept of risk. In this frame, the risk that any near-Earth object poses is typically seen through a lens that is a function of both the culture and the technology of human society. "NEOs have been understood differently throughout history." Each time an NEO is observed, "a different risk was posed, and throughout time that risk perception has evolved. It is not just a matter of scientific knowledge."[18]

Such perception of risk is thus "a product of religious belief, philosophic principles, scientific understanding, technological capabilities, and even economical resourcefulness."[18]

Risk scales

There are two schemes for the scientific classification of impact hazards from NEOs:
The annual background frequency used in the Palermo scale for impacts of energy greater than E megatonnes is estimated as:[19]
fB=0.03E0.8
For instance, this formula implies that the expected value of the time from now until the next impact greater than 1 megatonne is 33 years, and that when it occurs, there is a 50% chance that it will be above 2.4 megatonnes. This formula is only valid over a certain range of E.

However, another paper[20] published in 2002 – the same year as the paper on which the Palermo scale is based – found a power law with different constants:
fB=0.00737E0.9
This formula gives considerably lower rates for a given E. For instance, it gives the rate for bolides of 10 megatonnes or more (like the Tunguska explosion) as 1 per thousand years, rather than 1 per 210 years as in the Palermo formula. However, the authors give a rather large uncertainty (once in 400 to 1800 years for 10 megatonnes), due in part to uncertainties in determining the energies of the atmospheric impacts that they used in their determination.

Highly rated risks


Plot of orbits of known potentially hazardous asteroids (size over 460 feet (140 m) and passing within 4.7 million miles (7.6×10^6 km) of Earth's orbit) as of early 2013 (alternate image).

On 24 December 2004, minor planet 99942 Apophis (at the time known by its provisional designation 2004 MN4) was assigned a 4 on the Torino scale, the highest rating ever achieved. There was a 2.7% chance of Earth impact on 13 April 2029. However, on 28 December 2004, the risk of impact dropped to zero for 2029, but future potential impact solutions were still rated 1 on the Torino scale. The 2036 risk was lowered to a Torino rating of 0 in August 2006. The Palermo rating is −3.2.[21]

The only known NEO with a Palermo scale value currently greater than zero is (29075) 1950 DA, which may pass very close to or collide with the Earth (probability ≤ 0.003) in the year 2880. Depending on the unknown orientation of its axis of rotation, it will either miss the Earth by tens of millions of kilometers, or have a 1 in 300 chance of hitting the Earth. However, humanity has over 800 years to refine the orbit of (29075) 1950 DA, and to deflect it, if necessary.[22]

List of current threats

NASA maintains a continuously updated Sentry Risk Table of the most significant NEO threats in the next 100 years.[21] All or nearly all of the objects are highly likely to eventually drop off the list as more observations come in, reducing the uncertainties and enabling more accurate orbital predictions. (The list does not include (29075) 1950 DA, because that will not strike for at least 800 years.)[4][22]

History of NEO science and exploratory mission proposals

In a 2013 article in Wired Science, David Portree provides an overview of NEO science and proposed asteroidal missions, with an emphasis on the outcome of two conferences held in the 1970s. The International Astronomical Union minor planets workshop was held in Tucson, Arizona in March 1971 and a consensus "emerged that launching spacecraft to asteroids would be 'premature'."[17] "In January 1978, NASA’s Office of Space Science held a workshop at the University of Chicago to "assess the state of asteroid studies and consider options for the future."[17]

Of all of the near-Earth asteroids (NEA) that had been discovered by mid-1977, it was estimated that spacecraft could rendezvous with and return from only about one in 10 using less propulsive energy than is necessary to reach Mars. "Because even the most massive NEA—35 kilometres (22 mi)-wide 1036 Ganymed, discovered in 1924, has a very low surface gravity—landing and takeoff would need very little energy. This meant that a single spacecraft could sample multiple sites on any given NEA."[17] Overall, it was estimated that about one percent of all NEAs might provide opportunities for human-crewed missions, or no more than about ten known NEAs. Therefore, unless the NEA discovery rate were "immediately increased five-fold, no opportunity to launch 'astronaut-scientists' to an NEA was likely to occur within a decade of the Chicago workshop."[17]

Number and classification of near-Earth objects

Near-Earth objects are classified as meteoroids, asteroids, or comets depending on size and composition. Asteroids can also be members of an asteroid family, and comets create meteoroid streams that can generate meteor showers.

As of February 2014, 10,713 NEOs have been discovered:[8] 94 near-Earth comets and 10,619 near-Earth asteroids. Of those there are 815 Aten asteroids, 4,016 Amor asteroids, and 5,775 Apollo asteroids. There are 1,458 NEOs that are classified as potentially hazardous asteroids (PHAs).
Currently, 154 PHAs and 867 NEAs have an absolute magnitude of 17.75 or brighter, which roughly corresponds to at least 1 km in size.[8]

As of July 2014, there are 499 NEAs on the Sentry impact risk page at the NASA website.[21] A significant number of these NEAs – 215 as of May 2010 – are equal to or smaller than 50 meters in diameter and none of the listed objects are placed even in the "green/yellow zone" (Torino Scale 1-2), meaning that none warrant the attention of general public.[24] The JPL Small-Body Database lists 1,885 near Earth asteroids with an absolute magnitude (H) dimmer than 25 (roughly 50 meters in diameter).[25]

Near-Earth asteroids smaller than ~1 meter are near-Earth meteoroids and are listed as asteroids on most asteroid tables. The smallest known near-Earth meteoroid is 2008 TS26 with an absolute magnitude of 33[25] and estimated size of only 1 meter.[26]

Near-Earth asteroids


Near-Earth asteroids by size.

Near-Earth asteroids classification.

Cumulative discoveries of near-Earth asteroids known by size, 1980–2013.
There are significantly fewer near-Earth asteroids in the mid-size range than previously thought.

These are objects in a near-Earth orbit without the tail or coma of a comet. As of February 2015, 12,113 near-Earth asteroids are known,[8] ranging in size from 1 meter up to ~32 kilometers (1036 Ganymed). The number of near-Earth asteroids over one kilometer in diameter is estimated to be about 981.[9][27][28] The composition of near-Earth asteroids is comparable to that of asteroids from the asteroid belt, reflecting a variety of asteroid spectral types.[29]

NEAs survive in their orbits for just a few million years.[5] They are eventually eliminated by planetary perturbations, causing ejection from the Solar System or a collision with the Sun or a planet. With orbital lifetimes short compared to the age of the Solar System, new asteroids must be constantly moved into near-Earth orbits to explain the observed asteroids. The accepted origin of these asteroids is that asteroid-belt asteroids are moved into the inner Solar System through orbital resonances with Jupiter. The interaction with Jupiter through the resonance perturbs the asteroid's orbit and it comes into the inner Solar System. The asteroid belt has gaps, known as Kirkwood gaps, where these resonances occur as the asteroids in these resonances have been moved onto other orbits. New asteroids migrate into these resonances, due to the Yarkovsky effect that provides a continuing supply of near-Earth asteroids.[30] The asteroid with the greatest known chance of impacting Earth is 2010 RF12 with a 1 in 16 chance of impacting Earth on 5 September 2095.

A small number of NEOs are extinct comets that have lost their volatile surface materials, although having a faint or intermittent comet-like tail does not necessarily result in a classification as a near-Earth comet, making the boundaries somewhat fuzzy. The rest of the near-Earth asteroids are driven out of the asteroid belt by gravitational interactions with Jupiter.[5][31]

Near-Earth asteroids are divided into groups based on their semi-major axis (a), perihelion distance (q), and aphelion distance (Q):[2][5]
  • The Atiras or Apohele asteroids have orbits strictly inside Earth's orbit: an Atira asteroid's aphelion distance (Q) is smaller than Earth's perihelion distance (0.983 AU). That is, Q < 0.983 AU. (This implies that the asteroid's semi-major axis is also less than 0.983 AU.)
  • The Atens have a semi-major axis of less than 1 AU and cross Earth's orbit. Mathematically, a < 1.0 AU and Q > 0.983 AU.
  • The Apollos have a semi-major axis of more than 1 AU and cross Earth's orbit. Mathematically, a > 1.0 AU and q > 1.017 AU. (1.017 AU is Earth's aphelion distance.)
  • The Amors have orbits strictly outside Earth's orbit: an Amor asteroid's perihelion distance (q) is greater than Earth's aphelion distance (1.017 AU). Amor asteroids are also near-earth objects so q < 1.3 AU. In summary, 1.017 AU < q < 1.3 AU. (This implies that the asteroid's semi-major axis (a) is also larger than 1.017 AU.) Some Amor asteroid orbits cross the orbit of Mars.
(Note: Some authors define the Atens group differently: they define it as being all the asteroids with a semi-major axis of less than 1 AU. That is, they consider the Atiras to be part of the Atens.
Historically, until 1998, there were no known or suspected Atiras, so the distinction wasn't necessary.)

Because the Atens and all Apollos have orbits that cross Earth's orbit, they might impact the Earth. Atiras and Amors do not cross the Earth's orbit and are not immediate impact threats, but their orbits may change to become Earth-crossing orbits in the future.

Near-Earth comets

As of February 2015, 96 near-Earth comets have been discovered.[8] Although no impact of a comet in Earth's history has been conclusively confirmed, the Tunguska event may have been caused by a fragment of Comet Encke.[32] Cometary fragmenting may also be responsible for some impacts from near-Earth objects. It is rare for a comet to pass within 0.1 AU (15,000,000 km; 9,300,000 mi) of Earth.[33]

These near-Earth objects were probably derived from the Kuiper belt, beyond the orbit of Neptune.

Impact rate

Stony asteroids with a diameter of 4 meters (13 ft) impact Earth approximately once per year.[34]
Asteroids with a diameter of roughly 7 meters enter Earth's atmosphere with as much energy as Little Boy (the atomic bomb dropped on Hiroshima, approximately 15 kilotonnes of TNT) about every 5 years.[34] These ordinarily explode in the upper atmosphere, and most or all of the solids are vaporized.[35] Every 2,000–3,000 years, objects produce explosions of 10 megatons comparable to the one observed at Tunguska in 1908.[36] Objects with a diameter of one kilometer hit the Earth an average of twice every million year interval.[5] Large collisions with five kilometer objects happen approximately once every twenty million years.[34]

Assuming that these rates will continue for the next billion years, there exist at least 2,000 objects of diameter greater than 1 km that will eventually hit Earth. However, most of these are not yet considered potentially hazardous objects because they are currently orbiting between Mars and Jupiter. Eventually they will change orbits and become NEOs. Objects spend on average a few million years as NEOs before hitting the Sun, being ejected from the Solar System, or (for a small proportion) hitting a planet.[5]

Frequency of small asteroids roughly 1 to 20 meters in diameter impacting Earth's atmosphere.

Close approaches

On August 10, 1972, a meteor that became known as 1972 Great Daylight Fireball was witnessed by many people moving north over the Rocky Mountains from the U.S. Southwest to Canada. It was an Earth-grazing meteoroid that passed within 57 kilometers (about 34 miles) of the Earth's surface. It was filmed by a tourist at the Grand Teton National Park in Wyoming with an 8-millimeter color movie camera.[37]
On March 23, 1989, the 300-meter (1,000-foot) diameter Apollo asteroid 4581 Asclepius (1989 FC) missed the Earth by 700,000 kilometers (430,000 mi) passing through the exact position where the Earth was only 6 hours before. If the asteroid had impacted it would have created the largest explosion in recorded history, 12 times as powerful as the Tsar Bomba, the most powerful nuclear bomb ever exploded. It attracted widespread attention as early calculations had its passage being as close as 64,000 km (40,000 mi) from the Earth, with large uncertainties that allowed for the possibility of it striking the Earth.[38]

On March 18, 2004, LINEAR announced a 30-meter asteroid, 2004 FH, which would pass the Earth that day at only 42,600 km (26,500 mi), about one-tenth the distance to the Moon, and the closest miss ever noticed. They estimated that similar-sized asteroids come as close about every two years.[39]

On March 31, 2004, two weeks after 2004 FH, meteoroid 2004 FU162 set a new record for closest recorded approach, passing Earth only 6,500 km (4,000 mi) away (about one-sixtieth of the distance to the Moon). Because it was very small (6 meters/20 feet), FU162 was detected only hours before its closest approach. If it had collided with Earth, it probably would have harmlessly disintegrated in the atmosphere.

On March 2, 2009, near-Earth asteroid 2009 DD45 flew by Earth at about 13:40 UT. The estimated distance from Earth was 72,000 km (45,000 mi), approximately twice the height of a geostationary communications satellite. The estimated size of the space rock was about 35 meters (115 feet) wide.[40]

On January 13, 2010, at 12:46 UT, near-Earth asteroid 2010 AL30[41] passed at about 122,000 km (76,000 mi). It was approximately 10–15 m (33–49 ft) wide. If 2010 AL30 had entered the Earth's atmosphere, it would have created an air burst equivalent to between 50 kt and 100 kt (kilotons of TNT). The Hiroshima "Little Boy" atom bomb had a yield between 13-18 kt.[42]

On June 28, 2011, an asteroid designated 2011 MD, estimated at 5–20 m (16–66 ft) in diameter, passed within 20,000 km (12,000 mi) of the Earth, passing over the Atlantic Ocean.[43]

On November 8, 2011, (308635) 2005 YU55 (at about 400m diameter) passed within 324,600 km (201,700 mi) (0.85 lunar distances) of Earth. Ten weeks later, on January 27, 2012, the 10-metre wide asteroid 2012 BX34 passed a mere 60,000 km (37,000 mi) from Earth.[44]

On February 15, 2013, 367943 Duende (2012 DA14) passed approximately 27,700 km (17,200 mi) above the surface of Earth. This was closer than satellites in geosynchronous orbit. The asteroid was not visible to the unaided eye.

Future impacts

Although there have been a few false alarms, a number of objects have been known to be threats to the Earth. (89959) 2002 NT7 was the first asteroid with a positive rating on the Palermo Technical Impact Hazard Scale, with approximately one in a million on a potential impact date of approximately February 1, 2019; it is now known that 2002 NT7 will actually safely pass 0.4078 AU (61,010,000 km; 37,910,000 mi) from the Earth on January 13, 2019.[45]

Asteroid (29075) 1950 DA was lost after its discovery in 1950, since its observations over just 17 days were insufficient to determine its orbit, and then rediscovered on December 31, 2000. It has a diameter of about a kilometer (0.6 miles). The chance that it could impact Earth during its March 16, 2880 close approach had been estimated as 1 in 300. This is roughly 50% greater than the combined chance of impact for all other similarly large objects until 2880.[46] The next radar opportunity for 1950 DA is in 2032,[47] and will pinpoint our knowledge of the orbit, but additional optical position measurements have already reduced the probability of a 2880 impact to 1 in 20 000.

Only the asteroids 99942 Apophis (provisionally known as 2004 MN4) and (144898) 2004 VD17 have briefly had above-normal rankings on the Torino Scale.

Projects to minimize the threat

Several surveys have undertaken "Spaceguard" activities (an umbrella term), including Lincoln Near-Earth Asteroid Research (LINEAR), Spacewatch, Near-Earth Asteroid Tracking (NEAT), Lowell Observatory Near-Earth-Object Search (LONEOS), Catalina Sky Survey, Campo Imperatore Near-Earth Object Survey (CINEOS), Japanese Spaceguard Association, and Asiago-DLR Asteroid Survey. In 1998, the United States Congress mandated the Spaceguard Survey – detection of 90% of near-earth asteroids over 1 km diameter (which threaten global devastation) by 2008. In 2005, this was extended by the George E. Brown, Jr. Near-Earth Object Survey Act, which calls for NASA to detect 90% of NEOs with diameters of 140 meters or greater, by 2020.[48]

As of 2011, 911 of the largest (>1 km diameter) near-Earth asteroids have been found, with an estimate of 70 yet to be found.[9]
