    1835 Gajdariya, provisional designation 1970 OE, is a stony asteroid from the outer region of the asteroid belt, about 13 kilometers in diameter. It was discovered by Russian female astronomer Tamara Smirnova at Crimean Astrophysical Observatory in Nauchnyj on 30 July 1970.[8]

    The main-belt asteroid is a member of the Koronis family.[3] It orbits the Sun at a distance of 2.6–3.1 AU once every 4 years and 9 months (1,743 days). 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.[6][7]

    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.
