(7950) Berezov is an asteroid of the main outer belt , which was discovered by the Ukrainian astronomer Lyudmyla Shuravlowa on September 28, 1992 at the Crimean Observatory in Nautschnyj ( IAU code 095). There had been several sightings of the asteroid before: on September 29, 1958 under the provisional designation 1959 SE at the State Observatory in Heidelberg-Königstuhl , on December 23, 1982 (1982 YF 1 ) and on January 14, 1983 (1983 AP 3 ) in the Crimea -Observatory in Nautschnyj and on January 29, 1989 (1989 BB 2 ) at the Japanese observatory near Kushiro .
The mean diameter of the asteroid was determined to be 27.10 km (± 2.0). It has a dark surface with an albedo of 0.0663 (± 0.011).
Mean distance from the Sun ( major semiaxis ), eccentricity and inclination of the orbit plane of (7950) Berezov roughly correspond to the Eos family , a group of asteroids that typically have major semiaxes from 2.95 to 3.1 AU , bounded inward by the Kirkwood gap the 7: 3 resonance with Jupiter, as well as orbital inclinations between 8 ° and 12 °. The group is named after the asteroid (221) Eos . The family is believed to have emerged from a collision more than a billion years ago.
(7950) Berezov was named on May 4, 1999 after Berjosowo , an urban-type settlement in the West Siberian Khanty and Mansi Autonomous Okrug / Ugra . Berezov is the earlier English-language name for this place.
