274301 Wikipedia (/ˌwɪkiˈpdiə/ WIK-i-PEE-dee-ə), provisional designation 2008 QH24, is an asteroid orbiting in the inner region of the asteroid belt, approximately 1.3 kilometers (0.81 mi) in diameter. It was discovered on 25 August 2008 by astronomers at the Andrushivka Astronomical Observatory in northern Ukraine.[2] The asteroid was named after the online encyclopedia Wikipedia in January 2013.[1]

Discovery[edit]

Wikipedia was discovered by astronomers from the Andrushivka Astronomical Observatory (A50) in Ukraine, the country's only privately owned observatory,[5] which has discovered over 90 asteroids since 2003.[6] It was first observed by the Andrushivka team on 25 August 2008 at 22:47 UTC.[2] It was also observed on the next night and it received provisional designation 2008 QH24.[7] After it was also observed on 6 September by the Andrushivka team, the orbit of the asteroid was calculated accurately, it was shown that the asteroid 2008 QH24 was the same as 1997 RO4 and 2007 FK34 previously spotted by observatories Caussols-ODAS (France), Mt. Lemmon Survey and Steward Observatory (both in Arizona, U.S.).[2]

On 18 April 2011, Wikipedia received the number 274301,[8] the composition of the asteroid is not known but it is likely to consist, like other asteroids from the asteroid belt, of a mixture of rock and metal.[9]

Orbit[edit]

Wikipedia orbits the Sun at a distance of 2.0–2.7 AU (300–400 million km) once every 3 years and 8 months (1,342 days). Its orbit has an eccentricity of 0.15 and an inclination of 7° with respect to the ecliptic.[1] The asteroid's observation arc begins almost 11 years prior to its official discovery observation, with its first identification 1997 RO4 made by the ODAS survey in September 1997.[2]

Name[edit]

The decision of the Committee for Small Body Nomenclature to assign the name "Wikipedia" to the asteroid was published in the Minor Planet Circulars on 27 January 2013 (M.P.C. 82403).[10] The name was proposed by Andriy Makukha, a board member of Wikimedia Ukraine, it was submitted to the Committee by the owner of the observatory, Yuri Ivashchenko.[5] It reads:
