MINOR PLANET CIRCULAR

The 'Minor Planet Circulars' (MPCs) (also known as Minor Planets and Comets) are published generally on the date of each full moon by the Minor Planet Center. The Circulars contain astrometric observations, orbits and ephemerides of both minor planets and comets. The astrometric observations of comets are published in full, while the minor-planet observations are summarised by observatory code (the full observations now being given in the Minor Planet Circulars Supplement). New numberings and namings of minor planets, as well as numberings of periodic comets, are announced in the Circulars.
