Asteroids and TNOs with companions: component size ratio vs. separation

compiled by Wm. Robert Johnston

Component size ratio (Rs/Rp) is secondary radius divided by primary radius; separation (a/Rp) is expressed in terms of the radius of the primary. Some values are estimated based on assumed albedoes, densities, etc.
