It was discovered on 30 July 1970, by Russian astronomer Tamara Smirnova at Crimean Astrophysical Observatory in Nauchnyj, on the Crimean peninsula. It was named after Russian writer Arkady Gaidar. Characteristics 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. 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. Naming 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. Gaidar was killed in combat in October 1941. The official 1835 naming citation was published by the Minor Planet Center on 1 June 1975 (M.P.C. 3825). References 30em 2017-05-02 last obs.
