2072 Kosmodemyanskaya, provisional designation 1973 QE2, is a stony asteroid from the inner regions of the asteroid belt, about 8 kilometers in diameter. It was discovered by Russian female astronomer Tamara Smirnova at Crimean Astrophysical Observatory in Nauchnyj on 31 August 1973.[7]
The S-type asteroid orbits the Sun at a distance of 2.0–2.9 AU once every 3 years and 10 months (1,401 days). Its orbit shows an eccentricity of 0.16 and is tilted by 5 degrees to the plane of the ecliptic. It has a rotation period of 4.4 hours and an albedo of probably 0.2, even though preliminary results from the NEOWISE mission gave an exceptionally high value of 0.6805±0.1904.[4]
It 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]
