Themis family
A Hirayama family of asteroids in the outer part of the main asteroid belt at a mean distance of 3.13 AU from the Sun. It is one of the most populous and well-defined families, consisting of a core of large objects surrounded by a cloud of mostly smaller ones. The core includes (24) Themis, discovered in 1853 by the Italian astronomer Annibale de Gasparis (1819-1892), (62) Erato, (90) Antiope, (468) Lina, (526) Jena, and (846) Lipperta. Most family members are C-class asteroids with low albedos.
