(2208) Pushkin is an asteroid of the main inner belt that was discovered by the Soviet astronomer Nikolai Tschernych on August 8, 1978 at the Crimean Observatory in Nautschnyj ( IAU code 095). There had already been several unconfirmed sightings of the asteroid: for example, on April 22, 1968 under the provisional designation 1968 HU and on February 2, 1973 (1973 AN 3 ) at the Crimean observatory in Nautschnyj and in January and February 1978 at the observatory on the purple mountain near Nanjing (1978 WJ 14 ).
The asteroid belongs to the Cybele Group, a family of asteroids across the Hecuba Gap . The members' orbits are in 7: 4 resonance with the planet Jupiter , which stabilizes them. The group was named after the asteroid (65) Cybele . As an asteroid of spectral class D (2208) Pushkin has a reddish electromagnetic spectrum similar to carbonaceous chondrites with a very dark surface. The albedo was determined to be 0.0497 (± 0.008), the mean diameter to 38.31 (± 2.8) kilometers.
(2208) Pushkin was named on March 1, 1981 after Alexander Sergejewitsch Pushkin (1799–1837), the Russian national poet who is considered the founder of modern Russian literature . As early as 1976, an impact crater on the southern hemisphere of the planet Mercury was named after Alexander Pushkin: Mercury crater Pushkin .
