(274301) Wikipedia is an asteroid of the main inner belt . The asteroid was discovered in 2008 at the Andrushivka Astronomical Observatory in Haltschyn in the northern Ukrainian Oblast of Zhytomyr . In January 2013, the name of the asteroid was set based on the online encyclopedia of the same name on " Wikipedia ". It takes 3.68 years to orbit the sun from (274301) Wikipedia.

discovery

Andrushivka Astronomical Observatory (2012)

After the discovery on August 25, 2008 at 10:47 p.m. UTC in the 2001 built Andruschiwka Astronomical Astronomical Observatory ( IAU code A50), the asteroid continued to be observed and was given the provisional name 2008 QH 24 . On September 6, 2008, its orbit was calculated. It turned out that the asteroid was already on September 8, 1997 as 1997 RO 4 in the context of the OCA-DLR Asteroid Surveys at the French Observatoire de Calern (IAU code 910) and in 2007 as 2007 FK 34 from observatories in Arizona ( Mount Lemmon Survey with the IAU code G96 and at the Steward Observatory with the IAU code 691). On April 18, 2011 the asteroid was given the number (274301).

features

(274301) Wikipedia has an absolute brightness of 16.9 mag. Its composition, like the albedo , i.e. the reflectivity of the object, is not known. It orbits the sun every 3.68 years in a slightly eccentric orbit with an inclination of 6.7312 °. The point of its orbit closest to the sun ( perihelion ) has (274301) Wikipedia at 2.0327  AU , the point furthest from the sun ( aphelion ) at 2.7301 AU.

It is believed that (274301) Wikipedia could, in a broader sense, belong to the Vesta family , a large group of asteroids named after (4) Vesta , the second largest asteroid and third largest celestial body in the main belt. The timeless (not osculating ) orbital elements of (274,301) Wikipedia are almost identical to those of (in terms of absolute magnitude of 14.4 compared to 16.9) larger asteroid (21791) Mattweegman . Furthermore, the orbital elements of the somewhat larger (derived from the absolute brightness of 16.2, 16.0 and 16.3 compared to 16.9) asteroids (179728) 2002 RG 95 , (183281) 2002 TC 278 and (221025 ) are almost identical ) 2005 QA 21 .

Naming

The asteroid is named after the online dictionary Wikipedia. Wikipedia itself is a suitcase word from Wiki (originally Hawaiian for 'fast') and encyclopedia ( English for ' encyclopedia ').

The name suggestion for the asteroid came from a board member of the Wikimedia chapter Wikimedia Ukraine, Andrij Makucha. The proposal was submitted by the owner of the observatory, Yuri Ivashchenko. On January 27, 2013, the International Astronomical Union (IAU) unanimously accepted the name and published it.
