'''NGC 2''' is an [[intermediate spiral galaxy]] with the morphological type of Sab, located in the constellation of [[Pegasus (constellation)|Pegasus]]. NGC 2 was discovered by [[Lawrence Parsons, 4th Earl of Rosse]] on 20 August 1873."<ref name="cseligman">{{cite web|last1=Seligman|first1=Courtney|title=NGC 2 (= PGC 567)|url=http://cseligman.com/text/atlas/ngc0.htm#2|website=cseligman.com|access-date=16 November 2016}}</ref>

== Observational History ==
NGC 2 was first observed by [[Lawrence Parsons, 4th Earl of Rosse]] on 24 August 1873, and was described as "very faint, small, south of [[NGC 1|GC 1]]."<ref name="cseligman"/>

== Properties ==
[[File:NGC 1 and NGC 2 from the DESI Legacy Survey.jpg|thumb|left|NGC 1 and NGC 2 as an [[Double star|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 "[[Double star|optical double]]" as seen from Earth. <ref name="cseligman"/>

AGC 102559, a spiral galaxy 60,000 light-years in diameter, is the closest galaxy to NGC 2, only 1.8 million light-years from it. Although it is quite close to NGC 1, the latter is closer and unrelated to NGC 2.

NGC 2 is a [[spiral galaxy]] with a diameter of about 60  thousand light-years, smaller than the size of the [[Milky Way]].<ref name="Universe Guide">{{cite web|title=NGC 2 Galaxy Facts|url=https://www.universeguide.com/galaxy/ngc2|access-date=14 January 2023}}</ref>

== Listing in astronomical catalogues ==

NGC 2 is first cataloged as GC 6246, an addendum to Dreyer's 1877 Supplement to the General Catalogue of Nebulae And Clusters of Stars. The object is cataloged as [[Uppsala General Catalogue|UGC]] 59, [[Principal Galaxies Catalogue|PGC]] 567, [[Catalogue of Galaxies and Clusters of Galaxies|CGCG]] 478–027, and [[Morphological Catalogue of Galaxies|MCG]] +04-01-026.
