1074 Beljawskya, provisional designation 1925 BE, is an asteroid from the outer region of the asteroid belt, about 48 kilometers in diameter. It was discovered by Soviet–Russian astronomer Sergey Belyavsky at the Crimean Simeiz Observatory, on 26 January 1925.[9]
The dark asteroid is a member of the Themis family, a dynamical family of outer-belt asteroids with nearly coplanar ecliptical orbits. It orbits the Sun at a distance of 2.6–3.7 AU once every 5 years and 7 months (2,047 days). Its orbit shows an eccentricity of 0.18, tilted by only 1 degree to the plane of the ecliptic.[1]
In 2007, photometric light-curve observations by French astronomer Pierre Antonini have rendered a rotation period of 6.284±0.002 hours with a brightness amplitude of 0.37 in magnitude, which has been confirmed by a concurring observation at the Palomar Transient Factory survey in 2015.[7][8] Based on the surveys carried out by the Infrared Astronomical Satellite, IRAS, the Japanese Akari satellite, and the NEOWISE mission of the U.S. Wide-field Infrared Survey Explorer, the asteroid's surface has an albedo in the range of 0.06 to 0.08.[4][5][6] The Collaborative Asteroid Lightcurve Link classifies the dark Themistian asteroid as a S-type rather than a C-type body.[3]
The minor planet was named in honor of the discoverer Sergey Ivanovich Belyavsky (1883–1953), astronomer at the Simeis Observatory. The name was proposed by staff members of the observatory. Belyavsky discovered the brilliant comet C/1911 S3 and 36 numbered minor planets between 1912 and 1927.[2]
