1900 Katyusha, provisional designation 1971 YB, is a small but bright stony asteroid of the inner main-belt. It was discovered on December 16, 1971 by Russian astronomer Tamara Smirnova at the Crimean Astrophysical Observatory in Nauchnyj[6] and measures about 9 kilometers in diameter. Its albedo of 0.29 has been determined by spectrophotometric observations made by NEOWISE in 2010–2011.[4][5]
The asteroid orbits the Sun at a distance of 1.9–2.5 AU once every 3 years and 3 months (1,200 days)[1] and rotates around its axis with a period of nine and a half hours (9.4999±0.0001 h, 0.72±0.02 mag).[7] It is an assumed S-type asteroid belonging to the Flora family.[3]
Named in honor of Ukrainian Ekaterina Ivanovna 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]
