1804 Chebotarev  1804 Chebotarev ("prov. designation": ) is a stony background asteroid from the inner regions of the asteroid belt, approximately 10 kilometers in diameter. It was discovered on 6 April 1967, by Russian astronomer Tamara Smirnova at the Crimean Astrophysical Observatory in Nauchnyj on the Crimean peninsula. The asteroid was named after Soviet astronomer . The stony S-type asteroid orbits the Sun in the inner main-belt at a distance of 2.4–2.5 AU once every 3 years and 9 months (1,367 days). Its orbit has an eccentricity of 0.02 and an inclination of 4° with respect to the ecliptic. "Chebotarev" was first identified as at Yerkes Observatory in 1938, extending the body's observation arc by 29 years prior to its official discovery observation. In February 2004, a rotational lightcurve of "Chebotarev" was obtained from photometric observations by French amateur astronomer Laurent Bernasconi. It gave a well-defined rotation period of 4.026 hours with a brightness amplitude of 0.41 magnitude (). According to the survey carried out by NASA's Wide-field Infrared Survey Explorer with its subsequent NEOWISE mission, "Chebotarev" measures 9.15 kilometers in diameter, and its surface has a high albedo of 0.501, while the "Collaborative Asteroid Lightcurve Link" assumes a standard albedo for stony asteroids of 0.20 and calculates a diameter of 10.79 kilometers with an absolute magnitude of 12.2. This minor planet 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. The official was published by the Minor Planet Center on 1 January 1974 ().
