1835 Gajdariya, provisional designation1970 OE, is a stony Koronianasteroid from the outer region of theasteroid belt, approximately 12.5 kilometers in diameter.
It was discovered on 30 July 1970, by Russian astronomerTamara Smirnova atCrimean Astrophysical Observatory in Nauchnyj, on the Crimean peninsula.[10] It was named after Russian writerArkady Gaidar.[2]
TheS-type asteroid is a member of theKoronis family, which is named after158 Koronis and consists of about 300 known bodies with nearlyecliptical orbits. It orbits the Sun in theouter main-belt at a distance of 2.6–3.1 AU once every 4 years and 9 months (1,741 days). Its orbit has aneccentricity of 0.09 and aninclination of 1° with respect to the ecliptic.[1] Its spectra is that of anS-type asteroid with ageometric albedo of about 0.24. It has arotation period of 6.33 hours.[7][8]
It was named in honor of Soviet–Russian writer and children's authorArkady Gaidar (1904–1941), who joined the partisans and became a machine gunner during theNazi invasion of the Soviet Union.[2] Gaidar was killed in combat in October 1941. The officialnaming citation was published by theMinor Planet Center on 1 June 1975 (M.P.C. 3825).[11]
