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

compiled by Wm. Robert Johnston

last updated 13 October 2021

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

Component size ratio (R_{s}/R_{p}) is secondary radius divided by primary radius; separation (a/R_{h}) is expressed relative to the Hill radius. Some values are estimated based on assumed albedoes, densities, etc.
