Published by National Aeronautics and Space Administration | National Aeronautics and Space Administration | Metadata Last Checked: July 17, 2025 | Last Modified: 2025-07-17

We present data tables giving basic orbital and physical parameters for well-observed or suspected binary/multiple minor planets and the Pluto system, based on a literature review. In total 194 companions in 183 systems are included. Listed data include: minor planet number, name, provisional designation, and dynamical type; heliocentric orbit semimajor axis, eccentricity, and inclination; primary and secondary diameter; primary spin period and albedo; companion orbit semimajor axis and orbital period; system mass and density; secondary designation; discovery method and year of announcement; and year of last update. This data set is complete for binary/multiple components reported through 31 March 2010.
