2111 Tselina, provisional designation 1969 LG, is a stony Eoan asteroid from the outer regions of the asteroid belt, approximately 23 kilometers in diameter. It was discovered on 13 June 1969, by Soviet astronomer Tamara Smirnova at Crimean Astrophysical Observatory in Nauchnij, on the Crimean peninsula. It was later named after the Soviet  Virgin Lands Campaign.
Orbit and classification Tselina is a member of the Eos family ( ), the largest 606 asteroid family in the outer main belt consisting of nearly 10,000 asteroids.   : It orbits the Sun at a distance of 2.7–3.3 23 AU once every 5 years and 3 months (1,914 days). Its orbit has an eccentricity of 0.10 and an inclination of 11 ° with respect to the ecliptic.
Tselina was first observed as 1928 RS and 1928 SO by the German and Belgian observatories at Hamburg and Uccle, respectively. The body's observation arc begins at the discovering observatory in 1968, or one year prior to its official discovery.
Tholen classification, Tselina is a common stony S-type asteroid.
In September 2001, a rotational
lightcurve of Tselina was obtained by French amateur astronomer Laurent Bernasconi. Lightcurve analysis gave a well-defined rotation period of 6.563 hours with a brightness variation of 0.17 magnitude ( ). U=3 In September 2012, photometric observations by astronomers at the  Palomar Transient Factory, California, gave a concurring period of 6.562 hours with an amplitude of 0.29 magnitude ( ). U=2
Diameter and albedo
According to the surveys carried out by the Infrared Astronomical Satellite
IRAS, the Japanese Akari satellite, and NASA's Wide-field Infrared Survey Explorer with its subsequent NEOWISE mission, Tselina measures between 22.773 and 33.02 kilometers in diameter and its surface has an albedo between 0.13 and 0.226.    
Collaborative Asteroid Lightcurve Link agrees with the results obtained by IRAS, that is, an albedo of 0.1938 and a diameter of 24.54 kilometers with an absolute magnitude of 10.45.
minor planet was named after the tselina lands to commemorate the 25th anniversary of the Soviet Virgin Lands Campaign. The campaign was launched by  Nikita Khrushchev in 1953, with the intention to significantly increase the agricultural production in the USSR. The word "tselina" (or tseliny) means "virgin soil". The official naming citation was published by the Minor Planet Center on 1 April 1980 ( ). M.P.C. 5283
