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.", "identifier": "urn:nasa:pds:context_pds3:data_set:data_set.ear-a-compil-5-binmp-v2.0_vtjc-8ms5", "issued": "2018-06-26", "keyword": ["asteroid", "support-archives"], "landingPage": "https://pds.nasa.gov/ds-view/pds/viewDataset.jsp?dsid=EAR-A-COMPIL-5-BINMP-V2.0", "modified": "2025-07-17", "programCode": ["026:005"], "publisher": {"@type": "org:Organization", "name": "National Aeronautics and Space Administration"}, "references": ["https://pds.nasa.gov"], "theme": ["Earth Science"], "title": "BINARY MINOR PLANETS V2.0"}
