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

The asteroid was discovered on 31 August 1973, by Russian astronomer Tamara Smirnova at Crimean Astrophysical Observatory, Nauchnyj, on the Crimean peninsula.<ref name="MPC-Kosmodemyanskaya" /> It was named after Lyubov Kosmodemyanskaya, mother of Soviet heroes Zoya and Aleksandr.<ref name="springer" />

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.<ref name="jpldata" />

The asteroid was first identified as Template:Mp 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.<ref name="MPC-Kosmodemyanskaya" />

Physical characteristics

Kosmodemyanskaya has been characterized as a stony S-type asteroid.<ref name="lcdb" />

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 (Template:Small).<ref name="Binzel-1983b" /> 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 (Template:Small).<ref name="geneva-obs" />

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,<ref name="WISE" /><ref name="Masiero-2011" /> 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.<ref name="lcdb" />

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.<ref name="springer" /> The official naming citation was published by the Minor Planet Center on 1 April 1980 (Template:Small).<ref name="MPC-Circulars-Archive" />
