1793 Zoya, provisional designation 1968 DW, is a stony asteroid from the inner regions of the asteroid belt, about 9 kilometers in diameter. It was discovered on 28 February 1968 by Russian female astronomer Tamara Smirnova at the Crimean Astrophysical Observatory in Nauchnyj, Crimea.[7]
The asteroid is a member of the Flora family, a large group of stony S-type asteroids in the inner main-belt. It orbits the Sun at a distance of 2.0–2.4 AU once every 3 years and 4 months (1,211 days). Its orbit shows an eccentricity of 0.10 and is nearly coplanar to the plane of the ecliptic, inclined by only 2 degrees. It has a rotation period of 5.8 hours[5][6] and an albedo of 0.33 and 0.24, based on preliminary results from the WISE/NEOWISE mission and on assumptions made by the Collaborative Asteroid Lightcurve Link (CALL), respectively.[3][4]
It is named after Zoya Kosmodemyanskaya, Hero of the Soviet Union, partisan who died at the age of 18 during World War II in the Great Patriotic War. The minor planets 2072 Kosmodemyanskaya and 1977 Shura were named in honour of her mother and brother.[2]
