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, the Earth and the Moon,[5] and the dwarf planets Pluto, Eris, and Haumea and their respective moons.
