The Minor Planet Circulars (MPCs) is a scientific journal that is generally published on the date of each full moon by the Minor Planet Center. The Circulars contain astrometric observations, orbits and ephemerides of minor planets, comets and certain natural satellites. 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. New orbits for comets and natural satellites appear in the Circulars; new orbits for minor planets appear in the Minor Planets and Comets Orbit Supplement.
Famous quotes containing the words minor, planet and/or circular:
“A certain minor light may still
Leap incandescent
Out of kitchen table or chair
As if a celestial burning took
Possession of the most obtuse objects now and then—”
—Sylvia Plath (1932–1963)
“Mad? Is it mad that you destroy other people to save yourselves? You have done this. Is it mad that one country must destroy another to save themselves? You have also done this. How then is it mad that one planet must destroy another who threatens their very existence?”
—Edward D. Wood, Jr. (1922–1978)
“Oh Lolita, you are my girl, as Vee was Poe’s and Bea Dante’s, and what little girl would not like to whirl in a circular skirt and scanties?”
—Vladimir Nabokov (1899–1977)
