Please note that the MPC team is currently experiencing reduced staffing during the Christmas holidays. As a result, there might be delays in resolving medium and low priority helpdesk tickets. We appreciate your patience during this time. Urgent matters will be prioritized, but please expect longer response times than usual. Report problems or direct any questions here
The Minor Planet Center (MPC) is the single worldwide location for receipt and distribution of positional measurements of minor planets, comets and outer irregular natural satellites of the major planets. The MPC is responsible for the identification, designation and orbit computation for all of these objects. This involves maintaining the master files of observations and orbits, keeping track of the discoverer of each object, and announcing discoveries to the rest of the world via electronic circulars and an extensive website. The MPC operates at the Smithsonian Astrophysical Observatory, under the auspices of Division F of the International Astronomical Union (IAU).
All of the MPC's operating funds come from a NASA Near-Earth Object Observations program grant. Much of the computer equipment that the MPC uses was provided by the Tamkin Foundation.
