2010 Chebyshev, provisional designation 1969 TL4, is a rare-type carbonaceous asteroid from the outer regions of the asteroid belt, approximately 25 kilometers in diameter. The asteroid was discovered on 13 October 1969, by Soviet astronomer Bella Burnasheva at the Crimean Astrophysical Observatory in Nauchnyj, on the Crimean peninsula. It was named for mathematician Pafnuty Chebyshev.
Classification and orbit
Chebyshev orbits the Sun in the outer main-belt at a distance of 2.5–3.7 AU once every 5 years and 5 months (1,983 days). Its orbit has an eccentricity of 0.19 and an inclination of 2° with respect to the ecliptic. The asteroid was first identified as 1931 VA at Lowell Observatory in October 1931, extending the body's observation arc by 38 years prior to its official discovery observation at Nauchnyj.
Diameter and albedo
According to the survey carried out by the NEOWISE mission of NASA's space-based Wide-field Infrared Survey Explorer, Chebyshev measures 24.649 kilometers in diameter and its surface has an albedo of 0.065. Chebyshev has an absolute magnitude of 11.62.
This minor planet was named after Russian mathematician and mechanician Pafnuty Chebyshev (1821–1894). The official naming citation was published by the Minor Planet Center on 1 September 1978 (M.P.C. 4481). The lunar crater Chebyshev was also named in his honor.
