The Minor Planet Center (MPC) is the single worldwide location for the 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).
Here, you can find data as well as report on observations of asteroids, comets, minor planets, and satellites of the major planets.
