2139 Makharadze, provisional designation1970 MC, is a rare-type Nysaasteroid from the inner region of theasteroid belt, approximately 14 kilometres (8.7 mi) in diameter. It was discovered on 30 June 1970, by Russian astronomerTamara Smirnova at theCrimean Astrophysical Observatory in Nauchnyj.[5]
Makharadze belongs to theNysa family of asteroids. It orbits the Sun in theinner main-belt at a distance of 2.0–2.9 AU once every 3 years and 10 months (1,411 days). Its orbit has aneccentricity of 0.19 and aninclination of 2° with respect to theecliptic.[1]
In theTholen classification,Makharadze is aF-type asteroid.[1] It has a rotation period of 11.9759 hours with a brightness variation of 0.38magnitude.[3]
Thisminor planet was named after the Georgian city ofOzurgeti, formerly known as Makharadze. Makharadze is the twin city of Genichesk, Tamara Smirnova's Ukrainian birthplace.[2] The approved naming citation was published on 8 February 1982 (M.P.C. 6647).[6]
