The MP³C database

The aim of this database is to offer a user-friendly interface for exploring large databases of Minor Planets properties. Our ambition is to collect in a single place data of major interest that were scattered among several different databases, with a particular accent on physical properties. The output of our tool is multi-format and can also be exported toward Virtual Observatory utilities such as TOPCAT for subsequent exploitation. Newly discovered objects are added on a daily basis.


You can use two online services to access the MP³C catalogue with ADQL queries: WebService (VOTABLE format with bibliography) and TAP (multi formats without bibliography).

MP³C service is based on tools and protocols developed thanks to the efforts of the international astronomical community, through the International Virtual Observatory alliance (IVOA), which led to the construction of the Virtual Observatory. We are thankful, in particular, for the technical and human assistance brought by the European Virtual Observatory (EURO-VO) project and the Centre de Données astronomique de Strasbourg (CDS).
