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 2.6â3.1 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
It was named in honor of SovietâRussian writer and children's author Arkady Gaidar (1904â1941), 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]
