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. s are significant physical entities, associations or structures which current Science has confirmed to exist in Space. Astronomical catalogs are usually the result of an astronomical survey of some kind. Astronomical surveys generally involve imaging or mapping of regions of the sky using Telescopes.

Catalogs of historical importance
- Johann Bayer's Uranometria star atlas was published in 1603 with over 1200 stars. Johann Bayer (1572 &ndash March 7, 1625) was a German Astronomer and Lawyer. Uranometria is the short title of a star atlas produced by Johann Bayer. A Bayer designation is a stellar designation in which a specific star is identified by a Greek letter, followed by the genitive form of its parent constellation's Names are made of greek letters combined with constellation name, for example Alpha Centauri. Alpha Centauri (α Centauri / α Cen also known as Rigil Kentaurus, Rigil Kent, or Toliman, is the brightest Star in the southern Constellation
- John Flamsteed's Historia coelestis Britannica star atlas, published in 1725, lists stars using 2 digit numbers combined with constellation, for example 61 Cygni. John Flamsteed FRS ( 19 August, 1646 - 31 December, 1719) was an English Astronomer and the first Flamsteed designations for Stars are similar to Bayer designations except that they use numbers instead of Greek letters Not be confused with 16 Cygni, a more distant system containing two G-type stars harboring the Gas giant planet 16 Cygni Bb.
- Messier Catalog - Nebulae and Star Clusters was published in 1781, with objects M1 — M110. Charles Messier ( June 26, 1730 &ndash April 12, 1817) was a French astronomer most notable for publishing an The Messier objects are a set of Astronomical objects first listed by French astronomer Charles Messier in his "Catalogue des Nébuleuses The Messier objects are a set of Astronomical objects first listed by French astronomer Charles Messier in his "Catalogue des Nébuleuses The Messier objects are a set of astronomical objects catalogued by Charles Messier in his "Catalogue des Nébuleuses et des Amas d'Étoiles" ("Catalogue of Nebulae
- New General Catalogue compiled in the 1880s, lists objects NGC 0001 — NGC 7840. The New General Catalogue ( NGC) is the best-known catalogue of Deep sky objects in Amateur astronomy. The following is a list of objects in the New General Catalogue (NGC.
- Henry Draper Catalog published between 1918 and 1924, lists more than 225,000 of the brightest stars, named using HD followed by a 6-digit number. Henry Draper ( March 7, 1837 &ndash November 20 1882) was an American doctor and Astronomer. The Henry Draper Catalogue ( HD) is an Astronomical Star catalogue published between 1918 and 1924 giving Spectroscopic classifications
- 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. Sir Alfred Patrick Caldwell-Moore, CBE, HonFRS, FRAS (born 4 March 1923 in Pinner) known as Patrick Moore, is The Caldwell Catalogue is an Astronomical catalog of 109 bright Star clusters Nebulae and Galaxies
- 2MASS is the most ambitious project to map the night sky to date. Observations for the Two Micron All-Sky Survey ( 2MASS) began in 1997 and were completed in 2001 at two Telescopes located one each in the northern and Goals included first detection of brown dwarfs, an extensive survey of low mass stars, and cataloging of all detected stars and galaxies. More than 300 million point sources and 1 million extended sources were catalogued.
