    • The MPC Orbit (MPCORB) Database

    The MPC Orbit (MPCORB) database contains orbital elements of minor planets that have been published in the Minor Planet Circulars, the Minor Planet Orbit Supplement and the Minor Planet Electronic Circulars.

    At present MPCORB is not available via a non-ftp on this site.

    Information on the format of the elements is available via the Documentation page.

    Available Files

    MPCORB.DAT

    This includes all minor planet orbits excluding comets.
    MPCORB.DAT is available in either uncompressed or gzip-compressed form. The compressed file is about 30% the size of the uncompressed file.
