MP3C

The Minor Planet Physical Properties Catalogue (MP3C) collects and consolidates in a single database properties of asteroids and dwarf planets published by different sources.
It currently offers a web interface to different types of queries such as search for a body “ID card” with our best estimates of its properties, search for all measurements known for that body, or filtering on all minor bodies and all measurements by various criteria. Individual measurements are provided with their bibliographic reference. Most results can be exported as raw tabular text files easy to import in various software.

To query the database, simply choose a type of search in the top “Search” menu or enter an asteroid in the search bar.

MP3C 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 (VO). We are thankful, in particular, for the technical and human assistance brought by the European Virtual Observatory (EURO-VO) project and the Centre de Centre de Données astronomiques de Strasbourg (CDS).


Old MP3C

The older MP3C website is still available here. Note, however, that we will take it down at some point.
