Table information for 'mpc.epn_core'

General

Table Description: The EPN-TAP 2.0 version of the complete asteroid data from the Minor Planet Center (MPC), updated once per month. The MPC operates at the Smithsonian Astrophysical Observatory under the auspices of Division III of the International Astronomical Union (IAU). The MPC Orbit 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.

This table is available for ADQL queries and through the TAP endpoint.
