[2] The campaign was launched by Nikita Khrushchev in 1953, with the intention to significantly increase the agricultural production in the USSR.

[1] In September 2001, a rotational lightcurve of Tselina was obtained from photometric observations by French amateur astronomer Laurent Bernasconi.

[9] In September 2012, observations by astronomers at the Palomar Transient Factory, California, gave a concurring period of 6.562±0.0021 hours with an amplitude of 0.29 magnitude (U=2).

[5][6][7][8][10] The 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.
