List Of IC Objects
This is a partial list of IC objects, which are astronomical objects included in the ''Index Catalogue of Nebulae and Clusters of Stars''. This two volume catalog was published in 1895 and 1908 by John Louis Emil Dreyer, J. E. L. Dreyer. The constellation information for this table is available from the ''NGC2000.0: Complete New General Catalog and Index Catalog''. In some cases, the ''NASA/IPAC Extragalactic Database'' was used to confirm cross-identifications of galaxies. The remaining data is from the SIMBAD Astronomical Database unless otherwise noted. 1–999 1000–1999 2000–2999 3000–3999 4000–4999 5000–5386 See also * Lists of astronomical objects * List of NGC objects * Collinder catalogue * Lyon-Meudon Extragalactic Database * Melotte catalogue * New General Catalogue * Uppsala General Catalogue References Resources * * * * *{{citation , postscript=. , title=Index Catalog (IC) I / II Objects , last=Seligman , first=Courtney , work=Ce ...

Astronomical Object
An astronomical object, celestial object, stellar object or heavenly body is a naturally occurring physical entity, association, or structure that exists within the observable universe. In astronomy, the terms ''object'' and ''body'' are often used interchangeably. However, an astronomical body or celestial body is a single, tightly bound, contiguous entity, while an astronomical or celestial ''object'' is a complex, less cohesively bound structure, which may consist of multiple bodies or even other objects with substructures. Examples of astronomical objects include planetary systems, star clusters, nebulae, and galaxies, while asteroids, moons, planets, and stars are astronomical bodies. A comet may be identified as both a body and an object: It is a ''body'' when referring to the frozen nucleus of ice and dust, and an ''object'' when describing the entire comet with its diffuse coma and tail.
