Small-Body Satellites

Intro/Description

This page lists known and suspected natural satellites of small bodies. Suspected satellites are marked as [unconfirmed] in the “Satellite Notes” column. Publicly available orbital and physical properties of the satellites can be displayed in the table below by selecting the appropriate checkbox. Additional information might be available in the object page that can be reached by clicking on the object name.

Satellites of small-bodies are mainly discovered through radar observations (e.g., Margot et al. 2002, Science 296), lightcurve observations (e.g., Pravec et al. 2006, Icarus 181), and direct optical imaging (e.g., Brown and Margot 2001, IAUC 7588). The method of discovery for each satellite is described in the source listed in the “Satellite Reference” column. Most small-bodies with known satellites are binary systems, i.e, they have a single known satellite, but some systems have two or more satellites.
