Asteroid pairs and clusters

Asteroid pairs and clusters
compiled by Wm. Robert Johnston
last updated 9 July 2023

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

The following table lists 259 reported asteroid pairings, by ascending designation of the larger member of the pair. Measured diameters and albedos are provided; diameter values in parentheses are estimated assuming the same albedo between the pair (assumed albedo in parentheses). 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.
