2120 Tyumenia (
background asteroid, approximately 45 kilometers (28 miles) in diameter, located in the outer regions of the asteroid belt. It was discovered on 9 September 1967, by Soviet astronomer Tamara Smirnova at the Crimean Astrophysical Observatory in Nauchnyj, on the Crimean peninsula.[15] The asteroid was named for the now Russian district of Tyumen Oblast in Western Siberia.[2]
Orbit and classification
Tyumenia is a non-
Turku Observatory in November 1941, almost 26 years prior to its official discovery observation at Nauchnyj.[15]

Rotation period
Three rotational
Diameter and albedo
According to the surveys carried out by the Infrared Astronomical Satellite
albedo between 0.029 and 0.0819.[5][6][7][8][9][10][14] The Collaborative Asteroid Lightcurve Link derives an albedo of 0.0420 and a diameter of 40.93 kilometers based on an absolute magnitude of 11.0.[3]
