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.
