Asteroid Masses and Densities ASTEROID MASSES FROM THE

Abstract

Since 1989 both traditional groundbased techniques and modern spacecraft techniques have increased the number of asteroids with known masses from 4 to 24. At the same time, the shapes for 16 of these asteroids have been determined with sufficient precision to determine reliable volumes and bulk densities of these bodies. This review paper will look at the masses and densities that have been determined.
