854 Frostia is an asteroid orbiting the sun. It was discovered in 1916 by Sergey Ivanovich Belyavsky from Simiez Observatory in Crimea. It measures approximately 13.7km in diameter. It is named after Edwin Brant Frost, an American astronomer.
A satellite, designated S/2004 (854) 1, was identified based on lightcurve observations in July 2004 by Raoul Behrend, Laurent Bernasconi, Alain Klotz, and Russell I. Durkee. It is roughly 10 km in diameter and orbits about 25 km from Frostia with an orbital period of 1.5713 days.
