The Himalia group is a group of prograde irregular satellites of Jupiter, named after its largest member, Himalia. The group is thought to have formed from the fragmentation of a captured asteroid that was involved in a collision, making them a collisional family. Though they follow generally similar orbits, and the moons with measured colours appear compatible with a common origin, the dispersion of their orbital elements is too large to be conventionally explained, suggesting post-formation scattering of the satellites or a particular set of circumstances of their collisional event.
