Its orbit is tilted by 3 degrees to the plane of the ecliptic and shows an eccentricity of 0.09.A provisional light-curve analysis by Italian astronomer Silvano Casulli in 2010 has rendered a rotation period of 7000944000000000000♠9.44±0.01 hours with a brightness amplitude of 0.14 in magnitude. According to the survey carried out by the Japanese Akari satellite, and the Infrared Astronomical Satellite, IRAS, the asteroid's surface has an albedo of 0.028 and 0.035, with a corresponding diameter of 79.8 and 71.6 kilometers, respectively.The minor planet was named in honor of Aristarkh Belopolsky (1854–1934), astrophysicist at Pulkovo Observatory, the principal astronomical observatory of the Russian Academy of Sciences, located south of Saint Petersburg, Russia.
