    2072 Kosmodemyanskaya, provisional designation 1973 QE2, is a stony asteroid from the inner regions of the asteroid belt, approximately 6 kilometers in diameter.

    Contents

    The asteroid was discovered on 31 August 1973, by Russian astronomer Tamara Smirnova at Crimean Astrophysical Observatory, Nauchnyj, on the Crimean peninsula. [9] It was named after Lyubov Kosmodemyanskaya, mother of Soviet heroes Zoya and Aleksandr. [2]

    Classification and orbit

    Kosmodemyanskaya orbits the Sun in the inner main-belt at a distance of 2.1–2.9  AU once every 3 years and 10 months (1,402 days). Its orbit has an eccentricity of 0.16 and an inclination of 5° with respect to the ecliptic. [1]

    The asteroid was first identified as 1944 BD at Turku Observatory in 1944. Its first used observation is a precovery taken at Palomar Observatory in 1956, extending the body's observation arc by 17 years prior to the official discovery observation at Nauchnyj. [9]

    Physical characteristics

    Kosmodemyanskaya has been characterized as a stony S-type asteroid. [3]

    Lightcurves

    The first rotational lightcurve was obtained by American astronomer Richard P. Binzel during a photometric survey of small main-belt asteroids in the 1980s. It showed a rotation period of 4.4 hours with a brightness variation of 0.09 magnitude ( U=2 ). [6] In November 2004, another lightcurve of Kosmodemyanskaya was obtained by French amateur astronomer Laurent Bernasconi. Lightcurve analysis gave a period of 10 hours with an amplitude of 0.05 magnitude ( U=2- ). [7]

    Diameter and albedo

    According to the survey carried out by NASA's Wide-field Infrared Survey Explorer with its subsequent NEOWISE mission, Kosmodemyanskaya measures 4.843 kilometers in diameter and its surface has an exceptionally high albedo of 0.522, [4] [5] while the Collaborative Asteroid Lightcurve Link assumes a standard albedo for stony asteroids of 0.20 and calculates a diameter of 8.93 kilometers with an absolute magnitude of 12.61. [3]

    Naming

    This minor planet was named in memory of social worker Lyubov Kosmodemyanskaya (1900–1978), mother of Soviet heroes Zoya Kosmodemyanskaya and Aleksandr Kosmodemyansky. The minor planets 1793 Zoya and 1977 Shura, pet name for Aleksandr, were named after the two. [2] The official naming citation was published by the Minor Planet Center on 1 April 1980 ( M.P.C. 5282).
