1900 Katyusha (prov. designation: 1971 YB) is a stony background asteroid from the inner asteroid belt, approximately 9 kilometers in diameter. It was discovered on 16 December 1971, by Russian astronomer Tamara Smirnova at the Crimean Astrophysical Observatory in Nauchnyj, on the Crimean peninsula[7] and named in honor of Yekaterina Zelenko, the only woman to credited with conducting an aerial ramming.[2]

Orbit and classification
Katyusha 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]
Naming
This 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]
Physical characteristics
It rotates around its axis with a period of 9.4999 hours and with a brightness variation of 0.72 magnitude, indicating a non-spheroidal shape.[8]
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.[4][5][6] Katyusha has been characterized as a S-type asteroid.[3]
