Themis family

The Themis family (adj. Themistian; FIN: 602) is a family of carbonaceous asteroids located in the outer portion of the asteroid belt, at a mean distance of 3.13 AU from the Sun. It is one of the largest families with over 4700 known members, and consists of a well-defined core of larger bodies surrounded by a region of smaller ones. The collisional Themis family is named after its parent body, the asteroid 24 Themis, discovered on 5 April 1853 by Italian astronomer Annibale de Gasparis.

Description
The Themis family is one of the largest and longest-recognized dynamical families of asteroids, and is made up of C-type asteroids with a composition believed to be similar to that of carbonaceous chondrites. To date, the Themis family comprises approximately 535 known asteroids.

Asteroids in the Themis family share the following orbital elements:
 * semimajor axes between 3.08 AU and 3.24 AU
 * orbital eccentricities between 0.09 and 0.22
 * orbital inclinations of less than 3°
