An asteroid pair, or (if more than two bodies) an asteroid cluster, are asteroids which at some point in the past had very small relative velocities, and are typically formed either by a collisional break-up of a parent body, or from binary asteroids which became gravitationally unbound and are now following similar but different orbits around the Sun. A possible example of a pair are the Trojan asteroids 1583 Antilochus and 3801 Thrasymedes.
