It was discovered on 16 December 1971, by Russian astronomer Tamara Smirnova at the Crimean Astrophysical Observatory in Nauchnyj, on the Crimean peninsula[14] and named in honor of Yekaterina Zelenko, the only woman to have ever performed an aerial ramming.[2] Orbit and characterizationKatyusha is a member of the Flora family, one of the largest groups of stony asteroids in the inner main-belt.[3] It orbits the Sun in the inner main-belt at a distance of 1.9–2.5 AU once every 3 years and 3 months (1,200 days). Its orbit has an eccentricity of 0.13 and an inclination of 7° with respect to the ecliptic.[1]Physical characteristicsIt rotates around its axis with a period of {{val|9.4999}} hours and with a brightness variation of {{val|0.72}} magnitude, indicating a non-spheroidal shape.[18] According to the survey carried out by NASA's Wide-field Infrared Survey Explorer with its subsequent NEOWISE mission, Katyusha measures between 8.820 and 9 kilometers in diameter and its surface has an albedo between 0.29 and 0.299.[5][6] Katyusha has been characterized as a S-type asteroid.[3] NamingThis minor planet was named in honor of Ukrainian Yekaterina Zelenko (1916–1941), a war pilot and Hero of the Soviet Union, known for being the only woman who had ever executed an aerial ramming. The asteroid's name "Katyusha" is a petname for Ekaterina.[2] References1. ^1 2 3 {{cite journal |author = Masiero, Joseph R. |author2 = Mainzer, A. K. |author3 = Grav, T. |author4 = Bauer, J.
