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.
