    3409 Abramov, provisional designation 1977 RE6, is a stony Koronis asteroid from the outer region of the asteroid belt, approximately 11 kilometers in diameter. It was discovered on 9 September 1977, by Soviet–Russian astronomer Nikolai Chernykh at Crimean Astrophysical Observatory in Nauchnyj on the Crimean peninsula.[7]

    The S-type asteroid is a member of the Koronis family, a group consisting of about 200 known stony bodies with nearly ecliptical orbits. It orbits the Sun at a distance of 2.6–3.1 AU once every 4 years and 10 months (1,762 days). Its orbit has an eccentricity of 0.08 and an inclination of 1° with respect to the ecliptic.[1] The first precovery was obtained at Lowell Observatory in 1929, extending the asteroid's observation arc by 48 years prior to its discovery.[7]

    In 2008, a photometric light-curve analysis at the Universidad de Monterry Observatory, Mexico, gave a well-defined rotation period of 7.791±0.002 hours with a brightness amplitude of 0.50 in magnitude (U=3),[5] while an observation by astronomer René Roy rendered a tentative period of 9.0±0.4 hours (U=2).[6] According to the survey carried out by the NEOWISE mission of the NASA's space-based Wide-field Infrared Survey Explorer, the asteroid has an albedo of 0.24 with a corresponding diameter of 10.8 kilometers.[4] The Collaborative Asteroid Lightcurve Link and others closely agree with these findings.[3][lower-alpha 1]

    The minor planet was named in memory of Russian novelist and literary critic Fyodor Abramov (1920–1983), whose work focused on the difficult lives of the Russian peasant class.[2] Naming citation was published on 1 September 1993 (M.P.C. 22498).[8]
