854 Frostia is a main-beltasteroid orbiting theSun. It was discovered in 1916 bySergei Ivanovich Belyavsky fromSimeiz Observatory inCrimea and is named afterEdwin Brant Frost, an American astronomer. This asteroid measures approximately 8.4 km (5.2 mi) indiameter.[2]
Asatellite was identified based onlight curve observations in July 2004 byRaoul Behrend,Laurent Bernasconi,Alain Klotz, and Russell I. Durkee. It is roughly 10 km (6.2 mi) in diameter and orbits about 25 km (16 mi) from Frostia with anorbital period of 1.572 days.[3]
