1804 Chebotarev (prov. designation: Template:Mp) 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.[1] The asteroid was named after Soviet astronomer Template:Ill.[2]

Orbit and classification

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.[3] Chebotarev was first identified as Template:Mp at Yerkes Observatory in 1938, extending the body's observation arc by 29 years prior to its official discovery observation.[1]

Physical characteristics

Rotation period

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 (U=3Script error: No such module "Check for unknown parameters".).[4]

Diameter and albedo

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,[5] 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.[6]

Naming

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.[2] The official Template:MoMP was published by the Minor Planet Center on 1 January 1974 (M.P.C. 3569Script error: No such module "Check for unknown parameters".).[7]
