(4621) Tambov is an asteroid of the main inner belt that was discovered by the Soviet astronomer Nikolai Tschernych on August 17, 1979 at the Crimean Observatory in Nauchnyj ( IAU code 095). There had already been several unconfirmed sightings of the asteroid: on August 16, 1953 under the provisional designation 1953 QJ at the State Observatory in Heidelberg-Königstuhl , on August 12, 1964 (1964 PD) at the Goethe Link Observatory in Indiana, and on August 25 , 1964 . May 1971 (1971 KY) at the Crimean Observatory in Nautschnyj.
The mean diameter of the asteroid was calculated to be 5.741 (± 0.248) km .
The asteroid's solar orbit is highly elliptical with an eccentricity of 0.2114 . Mean distance from the sun ( major semi-axis ), eccentricity and inclination of the orbit plane of the asteroid lie within the respective limit values that are defined for the Nysa group, a group of asteroids named after (44) Nysa (also called Hertha family, according to (135) Hertha ).
(4621) Tambov was named after the Russian city of Tambov on April 25, 1994 .
