3409 Abramov, provisional designation 1977 RE6, is a stony asteroid from the outer region of the asteroid belt, about 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 stony S-type asteroid is a member of the Koronis family, a group consisting of about 200 known bodies. 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 is nearly co-planar to the plane of the ecliptic, tilted by only 1 degree, and shows an eccentricity of 0.08.[1]
In 2008, a photometric light-curve analysis at the Universidad de Monterry Observatory, Mexico, has given a rotation period of 7.791±0.002 hours with a brightness amplitude of 0.50 in magnitude, while an alternative, less accurate observation rendered a period of 9.0 hours.[5][6] According to the survey carried out by the NEOWISE mission of the U.S. 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 (CALL) closely agrees with these results.[3][4]
The minor planet was named in memory of Fyodor Abramov (1920–1983), well-known novelist and literary critic who depicted in his works the difficult lives of the Russian peasant class and fates of the ordinary people of northern Russia.[2]
