It was discovered on 30 July 1970, by Russian astronomer Tamara Smirnova at Crimean Astrophysical Observatory in Nauchnyj, on the Crimean peninsula.[10] It was named after Russian writer Arkady Gaidar.[2]
Characteristics edit
The S-type asteroid is a member of the Koronis family, which is named after 158 Koronis and consists of about 300 known bodies with nearly ecliptical orbits. It orbits the Sun in the outer main-belt at a distance of 2.6–3.1 AU once every 4 years and 9 months (1,741 days). Its orbit has an eccentricity of 0.09 and an inclination of 1° with respect to the ecliptic.[1] Its spectra is that of an S-type asteroid with a geometric albedo of about 0.24. It has a rotation period of 6.33 hours.[7][8]
Naming edit
It was named in honor of Soviet–Russian writer and children's author Arkady Gaidar (1904–1941), who joined the partisans and became a machine gunner during the Nazi invasion of the Soviet Union.[2] Gaidar was killed in combat in October 1941. The official naming citation was published by the Minor Planet Center on 1 June 1975 (M.P.C. 3825).[11]
