2093 Genichesk, provisional designation 1971 HX, is a Baptistina asteroid from the inner regions of the asteroid belt, approximately 12 kilometers in diameter. It was discovered on 28 April 1971, by Russian astronomer Tamara Smirnova at the Crimean Astrophysical Observatory in Nauchnyj, on the Crimean peninsula.[10] It was named for the Ukrainian town Henichesk.[2]

Orbit and classification

Genichesk is a member of the Baptistina family. It orbits the Sun in the inner main-belt at a distance of 1.9–2.7 AU once every 3 years and 5 months (1,249 days). Its orbit has an eccentricity of 0.17 and an inclination of 6° with respect to the ecliptic.[1] A first precovery was taken at Palomar Observatory in 1950, extending the body's observation arc by 21 years prior to its official discovery.[10]
