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.
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. The first precovery was obtained at Lowell Observatory in 1929, extending the asteroid's observation arc by 48 years prior to its discovery.
In 2008, a photometric light-curve analysis at the Universidad de Monterry Observatory, Mexico, gave a well-defined rotation period of 7000779100000000000♠7.791±0.002 hours with a brightness amplitude of 0.50 in magnitude (U=3), while an observation by astronomer René Roy rendered a tentative period of 7000900000000000000♠9.0±0.4 hours (U=2). 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. The Collaborative Asteroid Lightcurve Link and others closely agree with these findings.
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. Naming citation was published on 1 September 1993 (M.P.C. 22498).
