2093 Genichesk, provisional designation 1971 HX, is a dark, carbonaceous asteroid from the inner regions of the asteroid belt, about 12 kilometers in diameter. It was discovered by Russian female astronomer Tamara Smirnova at the Crimean Astrophysical Observatory in Nauchnyj on 28 April 1971.[7]
The asteroid is a member of the Baptistina family. It orbits the Sun at a distance of 1.9–2.7 AU once every 3 years and 5 months (1,249 days). Its orbit shows an eccentricity of 0.17 and is tilted by 6 degrees to the plane of the ecliptic. The C-type asteroid has an assumed geometric albedo of 0.06.[3]
Photometric observations at the Palmer Divide Observatory in Colorado (also see video § External links) during the winter of 2007–2008 were used to build a light-curve which gave a rotation period of 11.028±0.006 hours and a brightness variation of 0.24±0.02 in magnitude.[4] The results concur with observations made by Stéphane Charbonnel and Laurent Bernasconi, and with analysed data from the Palomar Transient Factory Survey in 2004 and 2015, respectively.[5][6]
The asteroid was named after the Ukrainian town Genichesk (Henichesk), the discoverer's birthplace in the former Ukrainian Soviet Socialist Republic[2]
