Combined Listing of Reported Asteroid/TNO Companions
by Date Reported

compiled by Wm. Robert Johnston
last updated 16 July 2017

This listing of other reported/postulated asteroid/TNO companions is incomplete. In some cases, subsequent analysis and/or observations have refuted the existence of a companion. Some diameter figures are triaxial dimensions from shape models which supercede the interpretations suggesting the presence of a companion. (Note that the delineation between the most likely candidates on this list and the least likely candidates on the previous page is ambiguous; corrections are welcome.)

Explanation: methods include AOT=adaptic optics telescope, HST=Hubble Space Telescope, LC=light curve, OCC=occultation, PER=period, RAD=radar, SP=space probe, SPEC=spectral, T=telescope.
