'''1900 Katyusha''' (''prov. designation'': {{mp|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<ref name="MPC-Katyusha" /> and named in honor of Yekaterina Zelenko, the only woman to credited with conducting an aerial ramming.<ref name="springer" />
== Orbit and classification ==
Katyusha is a member of the Flora family, one of the largest groups of stony asteroids in the inner main-belt.<ref name="LCDB" /> 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.<ref name="jpldata" />
== 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.<ref name="springer" />
== Physical characteristics ==
It 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.<ref name="Sada-2008b" />
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.<ref name="Masiero-2014" /><ref name="Masiero-2012" /><ref name="WISE" /> Katyusha has been characterized as a S-type asteroid.<ref name="LCDB" />
