It was discovered on 6 April 1967, by Russian astronomer Tamara Smirnova at the Crimean Astrophysical Observatory in Nauchnyj on the Crimean peninsula.[15] The asteroid was named after Soviet astronomer {{nowrap|G. A. Chebotarev}}.[2] Orbit and classificationThe 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 {{mp|1938 QL}} at Yerkes Observatory in 1938, extending the body's observation arc by 29 years prior to its official discovery observation.[15] Physical characteristicsRotation periodIn 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 ({{small|U=3}}).[7] Diameter and albedoAccording 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.[3] NamingThis 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 naming citation was published by the Minor Planet Center before November 1977 ({{small|M.P.C. 3569}}).[23] References1. ^1 2 3 {{cite book |title = Dictionary of Minor Planet Names – (1804) Chebotarev |last = Schmadel | first = Lutz D. |publisher = Springer Berlin Heidelberg |pages = 144–145 |date = 2007 |isbn = 978-3-540-00238-3 |doi = 10.1007/978-3-540-29925-7_1805 |chapter = (1804) Chebotarev }} [1][2][3][4][5][6][7]2. ^1 2 {{cite web |title = 1804 Chebotarev (1967 GG) |work = Minor Planet Center |url = http://www.minorplanetcenter.net/db_search/show_object?object_id=1804 |accessdate = 16 December 2016}} 3. ^1 {{cite web |title = MPC/MPO/MPS Archive |work = Minor Planet Center |url = http://www.minorplanetcenter.net/iau/ECS/MPCArchive/MPCArchive_TBL.html |accessdate = 16 December 2016}} 4. ^1 2 {{cite web |title = Asteroids and comets rotation curves – (1804) Chebotarev |last = Behrend |first = Raoul |publisher = Geneva Observatory |url = http://obswww.unige.ch/~behrend/page4cou.html#001804 |accessdate = 16 December 2016}} 5. ^1 2 3 4 5 6 {{cite web |title = LCDB Data for (1804) Chebotarev |publisher = Asteroid Lightcurve Database (LCDB) |url = http://www.minorplanet.info/PHP/GenerateALCDEFPage_Local.php?AstInfo=1804%7CChebotarev |accessdate = 16 December 2016}} 6. ^1 2 3 4 {{cite journal |display-authors = 6 |first1 = Joseph R. |last1 = Masiero |first2 = A.
