3409 Abramov, provisional designation 1977 RE6, is a stony Koronian 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. [8] The asteroid was named after Russian writer Fyodor Abramov. [2]
Orbit and classification
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 in the outer main-belt at a distance of 2.6–3.1 AU once every 4 years and 10 months (1,761 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. [8]
Physical characteristics
Lightcurves
In 2008, a photometric lightcurve 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), [6] while an observation by astronomer René Roy rendered a tentative period of 9.0±0.4 hours ( U=2). [7]
Diameter and albedo
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] [5] The Collaborative Asteroid Lightcurve Link and others closely agree with these findings. [3] [a]
Naming
This 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] The official naming citation was published by the Minor Planet Center on 1 September 1993 ( M.P.C. 22498). [9]
