The Minor Planet Center operates at the Smithsonian Astrophysical Observatory (SAO), which is part of the Center for Astrophysics (CfA) along with the Harvard College Observatory (HCO).
Under the auspices of the International Astronomical Union, it is the official organization in charge of collecting observational data for minor planets (asteroids) and comets, calculating their orbits and publishing this information via the Minor Planet Circulars. It runs a number of free on-line services for observers to assist them in observing minor planets and comets. The complete catalogue of minor planet orbits (MPCORB, sometimes referred to as the 'Minor Planet Catalogue') may also be freely downloaded.
The Minor Planet Center was set up at the University of Cincinnati in 1947, under the direction of Paul Herget. Upon Herget's retirement in 1978, the MPC was moved to the SAO, under the direction of Brian Marsden. Since 2006, the director of the MPC is Timothy B. Spahr, who oversees a staff of 5.
Famous quotes containing the words minor, planet and/or center:
“To minor authors is left the ornamentation of the commonplace: these do not bother about any reinventing of the world; they merely try to squeeze the best they can out of a given order of things, out of traditional patterns of fiction.”
—Vladimir Nabokov (1899–1977)
“Spring is strong and virtuous,
Broad-sowing, cheerful, plenteous,
Quickening underneath the mould
Grains beyond the price of gold.
So deep and large her bounties are,
That one broad, long midsummer day
Shall to the planet overpay
The ravage of a year of war.”
—Ralph Waldo Emerson (1803–1882)
“Every beloved object is the center point of a paradise.”
—Novalis [Friedrich Von Hardenberg] (1772–1801)
