4936 Butakov, provisional designation 1985 UY4, is a stony asteroid from the inner regions of the asteroid belt, about 5 kilometers in diameter. It was discovered on 22 October 1985, by Soviet–Ukrainian female astronomer Lyudmila Zhuravlyova at the Crimean Astrophysical Observatory in Nauchnyj on the Crimean peninsula.[8]
The S-type asteroid is a member of the Flora family, one of the largest groups of stony asteroids in the main-belt. It orbits the Sun at a distance of 2.0–2.6 AU once every 3 years and 5 months (1,254 days). Its orbit shows an eccentricity of 0.13 and is tilted by 6 degrees to the plane of the ecliptic.[1]
According to the survey carried out by the U.S. Wide-field Infrared Survey Explorer with its NEOWISE mission, the asteroid's surface has a notably high albedo of 0.36, while the Collaborative Asteroid Lightcurve Link assumes a more moderate value of 0.24, which is also identical to the albedo of the Flora family's namesake, the asteroid 8 Flora.[3][4] Two photometric light-curve analysis rendered rotation period of 13.8 and 13.9 hours, respectively, with a third observation that gave a divergent period of 19.2 hours.[5][6][7]
The minor planet was named in memory of Russian admiral Grigory Butakov (1820–1882), who fought in the Crimean War and drew up the first systematic directions for sailing in the Black Sea. In 1856 he became commander-in-chief of the Black Sea Fleet and the military governor of Nikolaev and Sevastopol. The minor planet 2121 Sevastopol is named after the city on the Crimean peninsula.[2] Butakov is widely credited as being the father of steam-powered ship tactics during the 19th century.
