NGC 2022 is a planetary nebula in the equatorial constellation of Orion, located at a distance of 8.21 kilolight-years from the Sun. [3] It was first observed by William Herschel on December 28, 1785, who described it as: considerably bright, nearly round, like a star with a large diameter, like an ill-defined planetary nebula.

NGC 2000.0 (also known as the Complete New General Catalog and Index Catalog of Nebulae and Star Clusters) is a 1988 compilation of the NGC and IC made by Roger W. Sinnott, using the J2000.0 coordinates. [17] [18] It incorporates several corrections and errata made by astronomers over the years. [5]

SN 2022jli is a Type Ic supernova discovered in 2022 in the spiral galaxy NGC 157 at a distance of about 23 Mpc. The light curve of the supernova exhibited oscillations that are interpreted as an interaction of a companion star of the star that exploded with a compact object, probably a neutron star or a black hole.

The NGC 1 and 2 pair are not physically related. NGC 1 lies at a distance of ~200 million l.y. with NGC 2 at roughly 320 million l.y. [5] The initial observers missed NGC 2, which is much fainter. NGC 1 appears to be quite close to NGC 2, in reality however, the two objects are far apart and unrelated. NGC 2 was first observed as a "companion ...
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.

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 ...
