(2979) Murmansk is an asteroid of the main outer belt , which was discovered by the Ukrainian - Soviet astronomer Lyudmyla Shuravlowa on October 2, 1978 at the Crimean Observatory in Nautschnyj ( IAU code 095). An unconfirmed sighting of the asteroid had already occurred on April 23, 1976 at the Crimean Observatory in Nautschnyj under the provisional designation 1976 HM.
The mean diameter of the asteroid was calculated to be around 21 km. It has a dark surface with an albedo of 0.05.
According to the SMASS classification ( Small Main-Belt Asteroid Spectroscopic Survey ), a spectroscopic study by Gianluca Masi , Sergio Foglia and Richard P. Binzel at (2979) Murmansk also assumed a dark surface, so roughly speaking it could be be a C asteroid .
(2979) Murmansk was named after the city of Murmansk on July 13, 1984 .
