These lunar rocks were ejected into space when another (asteroidal or cometary) object collided with the Moon with enough force to launch some of the impact-produced debris into Earth-crossing orbits.
Lunar meteorites are identified by their unique chemical and mineral characteristics indicative of their origin on the Moon, mainly based on comparison to lunar rocks returned to Earth by the Apollo and Luna missions.
