2094 Magnitka, provisional designation 1971 TC2, is a stony asteroid from the inner regions of the asteroid belt, about 13 kilometers in diameter. It was discovered at and by the Crimean Astrophysical Observatory in Nauchnyj on 12 October 1971.[10] The discovery has not been attributed to an observing astronomer.
The asteroid belongs to the Flora family of stony asteroids, one of the larger groups known to dwell in the inner-main belt. It orbits the Sun at a distance of 2.0–2.4 AU once every 3 years and 4 months (1,218 days). Its orbit shows an eccentricity of 0.10 and is tilted by 5 degrees to the plane of the ecliptic. The S-type asteroid has a rotation period of 6.112 hours and an albedo in the range of 0.12–0.28, according to analyzed data from the surveys carried out by IRAS, Akari, WISE and NEOWISE.[4][5][6][7][8]
It was named for the city of Magnitogorsk, one of the largest centers of metallurgy of the former Soviet Union.[2] It is located at the far-east of the Ural Mountains in the Chelyabinsk Oblast region, also known for the spectacular air-burst of the Chelyabinsk meteor in 2013.
