    • BINARY MINOR PLANETS V2.0

    Metadata Updated: August 22, 2025

    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 173 companions in 165 systems are included. Listed data include: minor planet number, name, and provisional designation, dynamical type, and heliocentric semimajor axis and eccentricity; primary and secondary diameter; primary spin period and albedo; companion semimajor axis and orbital period; system mass and density; secondary designation; discovery method and year of announcement. This data set is complete for binary/multiple components reported through 10 March 2009, with some additional data through 4 May 2009.
