Cybele asteroid

The Cybele asteroids are in the outer main belt (shown in white), but inside of the Hilda family (brown).

Cybele asteroids are a group of asteroids in the outer asteroid belt with a semi-major axis between 3.27 AU and 3.7 AU, an eccentricity less than 0.3, and an inclination less than 25°. The group is named for the asteroid 65 Cybele.^[1] As of 2010, the group is thought to have formed from the breakup of a larger object in the distant past.^[1]

Some of the largest Cybele asteroids are 87 Sylvia, 65 Cybele (the group's namesake),^[1] 107 Camilla, 121 Hermione, 76 Freia, 790 Pretoria, and 566 Stereoskopia. Some of the group also have asteroid moons, such as 121 Hermione.^[1]
