2139 Makharadze, provisional designation 1970 MC, is a main-belt asteroid discovered on June 30, 1970 by Russian astronomer Tamara Smirnova at the Crimean Astrophysical Observatory in Nauchnyj.[4] The F-type asteroid orbits the Sun at a distance of 2.0–2.9 AU once every 3 years and 10 months (1,412 days) and has a rotation period of 12 hours.[1] It belongs to the Nysa family of asteroids and its diameter has been calculated to measure about 8 kilometers.[3]

The asteroid is named after the Georgian city of Ozurgeti, formerly known as Makharadze. Makharadze is the twin city of Genichesk, Tamara Smirnova's Ukrainian birthplace.[2]
