(3406) Omsk is an asteroid located in the central main belt . He was on 21 February 1969 by the Soviet astronomer Bella Burnaschewa the Crimean Astrophysical Observatory in Nautschnyj ( IAU code discovered 095). The asteroid had already been sighted on May 29, 1951 under the provisional designation 1951 KA 1 at the McDonald Observatory in Texas .
The mean diameter of (3406) Omsk was calculated to be 16.058 (± 0.217) kilometers, the albedo as 0.224 (± 0.023).
According to the SMASS classification ( Small Main-Belt Asteroid Spectroscopic Survey ), a spectroscopic study by Gianluca Masi , Sergio Foglia and Richard P. Binzel subdivided all investigated asteroids into C, S and V types (3406) Omsk assigned to the C asteroids . In an analysis according to SMASSII by the Pan-STARRS telescope system , however, the asteroid was assigned to type X and in an analysis of data from the Wide-Field Infrared Survey Explorer to type M.
The asteroid's period of rotation was observed from May 11-19 , 2007 in New South Wales by Colin Bembrick at the Mount Tarana Observatory in Bathurst and Greg Crawford at the Bagnall Beach Observatory in Corlette . The light curve gave a rotation period of 7.275 h (± 0.006).
Mean distance from the Sun ( major semiaxis ), eccentricity and inclination of the orbit plane of (3406) Omsk roughly correspond to the Dora family, a group of asteroids named after (668) Dora . However, the asteroid does not belong to any asteroid family.
(3406) Omsk was named on February 18, 1992 after the Siberian city of Omsk , the birthplace of Bella Burnasheva.
