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)
“And so I look on those sentiments which make the glory of the human being, love, humility, faith, as being also the intimacy of Divinity in the atoms; and, that, as soon as the man is right, assurances and previsions emanate from the interior of his body and his mind; as, when flowers reach their ripeness, incence exhales from them, and, as a beautiful atmosphere is generated from the planet by the averaged emanations from all its rocks and soils.”
—Ralph Waldo Emerson (1803–1882)
“Loving a baby is a circular business, a kind of feedback loop. The more you give the more you get and the more you get the more you feel like giving.”
—Penelope Leach (20th century)
