Belopolskya (
minor planet designation: 1004 Belopolskya), provisional designation 1923 OS, is a dark Cybele asteroid from the outermost region of the asteroid belt, approximately 75 kilometers (47 mi) in diameter. It was named for Russian astrophysicist Aristarkh Belopolsky
.
Discovery
Belopolskya was discovered on 5 September 1923, by Russian astronomer
Heidelberg in Germany.[2]
It was first identified as A917 TA at Simeiz in 1917. The body's observation arc begins with the above-mentioned Heidelberg-observation following its official discovery.[8]
Classification and orbit
Belopolskya orbits the Sun at a distance of 3.1–3.7
Cybele asteroids, a dynamical group named after one of the largest asteroids, 65 Cybele
.
Physical characteristics
Belopolskya is classified as a PF-type asteroid in the
Tholen taxonomy, a subtype of the dark and reddish P-type asteroids. A few dozens of these bodies are known, most of them are Jupiter trojans or reside in the outermost main-belt.[9]
Diameter and albedo
According to the surveys carried out by the Infrared Astronomical Satellite
albedo of 0.0348 and 0.028, respectively.[4][5] The Collaborative Asteroid Lightcurve Link adopts the shorter diameter obtained by IRAS.[3]
