1804 Chebotarev, provisional designation 1967 GG, is a bright asteroid dwelling in the inner regions of the main-belt. It was discovered on 6 April 1967 by Russian female astronomer Tamara Smirnova at the Crimean Astrophysical Observatory in Nauchnyj.[6]
The stony S-type asteroid measures about 10 kilometers in diameter. It orbits the Sun at a distance of 2.4–2.5 AU once every 3 years and 9 months (1,368 days). A preliminary analysis by the WISE/NEOWISE missions published an exceptionally high, yet very uncertain albedo of 0.501±0.289, while the LCDB project assumes a much lower value of 0.20.[3][4] The body rotates around its axis every 4.03 hours.[5]
It was named in honor of G. A. Chebotarev (1913–1975), who was a professor and the director of the Institute of Theoretical Astronomy as well as president of IAU's Commission 20 (Positions & Motions of Minor Planets, Comets & Satellites). He is known for his work on celestial mechanics of asteroids, comets and satellites.[2]
