Collisional family

Diagram showing the similarities between the satellites of each of the outer groups of Jovian moons

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.
