2010 Chebyshev, provisional designation1969 TL4, is a rare-type carbonaceousasteroid from the outer regions of theasteroid belt, approximately 25 kilometers in diameter. The asteroid was discovered on 13 October 1969, by Soviet astronomerBella Burnasheva at theCrimean Astrophysical Observatory in Nauchnyj, on the Crimean peninsula.[4] It was named for mathematicianPafnuty Chebyshev.[2]
Chebyshev orbits the Sun in theouter main-belt at a distance of 2.5–3.7 AU once every 5 years and 5 months (1,983 days). Its orbit has aneccentricity of 0.19 and aninclination of 2° with respect to theecliptic.[1] The asteroid was first identified as1931 VA atLowell Observatory in October 1931, extending the body'sobservation arc by 38 years prior to its official discovery observation at Nauchnyj.[4]
In theTholen classification,Chebyshev is a rare BU: type, a variation of the carbonaceousB-type asteroids.[1]
According to the survey carried out by theNEOWISE mission of NASA's space-basedWide-field Infrared Survey Explorer,Chebyshev measures 24.649 kilometers in diameter and its surface has analbedo of 0.065.[3]Chebyshev has anabsolute magnitude of 11.62.[1]
As of 2017,Chebyshev'rotation period and shape remain unknown.[1][5]
Thisminor planet was named after Russian mathematician and mechanicianPafnuty Chebyshev (1821–1894).[2] The officialnaming citation was published by theMinor Planet Center on 1 September 1978 (M.P.C. 4481).[6] The lunar craterChebyshev was also named in his honor.
