NGC 1 and NGC 2 as an optical double. NGC 2 is located about 345 million light-years from the Solar System, with a magnitude of +14.2, while the distance to NGC 1 is 210 million light-years. Although visually close in the sky, NGC 1 and NGC 2 are at very different distances; were they stars, they would be referred to as an "optical double" as ...
The following is a list of NGC objects, that is objects listed in the New General Catalogue (NGC). It is one of the largest comprehensive astronomical catalogues for deep sky objects such as star clusters, nebulae, and galaxies.

Triangulum Galaxy (M33, NGC 598) 5.7 2.9 Mly (890 kpc) Triangulum: Being a diffuse object, its visibility is strongly affected by even small amounts of light pollution, ranging from easily visible in direct vision in truly dark skies to a difficult averted vision object in rural/suburban skies.

The NGC contains 7,840 objects, including galaxies, star clusters and emission nebulae. Dreyer published two supplements to the NGC in 1895 and 1908, known as the Index Catalogues (abbreviated IC), describing a further 5,386 astronomical objects. Thousands of these objects are best known by their NGC or IC numbers, which remain in widespread use.
Méchain later concluded that this object was simply a re-observation of M101, though some sources suggest that the object Méchain observed was the galaxy NGC 5866 and identify that as M102. [ 12 ] Messier's final catalogue was included in the Connaissance des Temps pour l'Année 1784 [ Knowledge of the Times for the Year 1784 ], the French ...
NGC 1602 is a barred irregular galaxy in the constellation Dorado. The galaxy lies about 65 million light years away from Earth, which means, given its apparent dimensions, that NGC 1602 is approximately 50,000 light years across. [1] It was discovered by John Herschel on December 5, 1834. [3] It is a member of the Dorado Group. [4]
