2121 Sevastopol, provisional designation 1971 ME, is a stony Florian asteroid and synchronous binary system from the inner regions of the asteroid belt, approximately 10 kilometers in diameter. It was discovered on 27 June 1971, by Russian astronomer Tamara Smirnova at the Crimean Astrophysical Observatory in Nauchnij, on the Crimean peninsula. [7] Its minor-planet moon was discovered in 2010.
Sevastopol is a member of the Flora family, one of the largest groups of stony asteroids in the main-belt. It orbits the Sun in the inner main-belt at a distance of 1.8–2.6 AU once every 3 years and 3 months (1,179 days). Its orbit has an eccentricity of 0.18 and an inclination of 4° with respect to the ecliptic. [1]
In 2010, a minor-planet moon, designated S/2010 (2121) 1, was discovered around Sevastopol, orbiting at a distance of 26 kilometers with a diameter of 3.54 ± 0.17 km. [5]
The asteroid was named after the Crimean city on the 200th anniversary of its foundation. [3] The approved naming citation was published by the Minor Planet Center on 28 January 1983 ( M.P.C. 7616). [8]
