Collisional family
Type of group of minor planets
From Wikipedia, the free encyclopedia
In astronomy, a collisional family is a group of objects that are thought to have a common origin in an impact (collision). They have similar compositions and most share similar orbital elements.

Known or suspected collisional families include numerous asteroid families,[1][2][3][4] most of the irregular moons of the outer planets, and the dwarf planet Haumea.
