Asteroid Pairs

(under construction)
compiled by Wm. Robert Johnston
last updated 25 March 2016

Recent dynamical studies have identified pairs of asteroids which had very small (~meters/second) relative velocities at some point in the past. Many of these may represent former binary asteroids where the pair became gravitationally unbound and subsequently followed separate orbits around the Sun. Another possible cause is collisional breakup of a parent asteroid.

The following table lists 135 reported asteroid pairs, with designation ascending from left to right columns. A few families are suggested; members are listed pair-wise with the lowest designated family member. In the notes column, "spurious" indicates likely false pairs (i.e. not of common origin) and asteroid family membership is indicated where applicable. Sources are listed below.
