Astronomical catalogue

An astronomical catalog or catalogue is a list or tabulation of astronomical objects, typically grouped together because they share a common type, morphology, origin, means of detection, or method of discovery. Astronomical catalogs are usually the result of an astronomical survey of some kind.

Catalogs of historical importance

Template:See

  • Azophi's Book of Fixed Stars, published in 964, describes more than a thousand stars in detail and provides the first descriptions of the Andromeda Galaxy[1] and the Large Magellanic Cloud.[2][3]
  • Johann Bayer's Uranometria star atlas was published in 1603 with over 1200 stars. Names are made of Greek letters combined with constellation name, for example Alpha Centauri.
  • John Flamsteed's Historia coelestis Britannica star atlas, published in 1725, lists stars using numbers combined with constellation and ordered by right ascension, for example 61 Cygni.
  • Messier Catalog - The Messier objects are a set of astronomical objects first listed by French astronomer Charles Messier in 1771. Nebulae and Star Clusters was published in 1781, with objects M1 – M110.
  • New General Catalogue compiled in the 1880s by J. L. E. Dreyer, lists objects NGC 0001 – NGC 7840. The NGC is one of the largest comprehensive catalogues, as it includes all types of deep space objects and is not confined to, for example, galaxies.
  • Henry Draper Catalogue published between 1918 and 1924, lists more than 225,000 of the brightest stars, named using HD followed by a 6-digit number.
  • Sir Patrick Moore compiled the Caldwell catalogue in 1995 to complement the Messier catalog, listing 109 bright star clusters, nebulae, and galaxies named C1 to C109. (This is a list of favorite deep-sky objects and not a catalog in the astronomical sense. Other deep-sky observing lists for amateur astronomers predated it.)
  • 2MASS is the most ambitious project to map the night sky to date. Goals included first detection of brown dwarfs, an extensive survey of low mass stars, and cataloguing of all detected stars and galaxies. More than 300 million point sources and 1 million extended sources were catalogued.
