NGC 2 is a spiral galaxy in the constellation Pegasus, discovered by Lawrence Parsons, 4th Earl of Rosse on 20 August 1873, and was described as "very faint, small, south of NGC 1."[3] It lies slightly to the south of NGC 1. It is a faint spiral galaxy of apparent magnitude 14.2.[1]

NGC 2 is about 115,000 light years in diameter, but is 3 to 5 times more luminous than the Milky Way as it is quite compact. AGC 102559, a galaxy 60,000-light-years in diameter, is the closest galaxy to NGC 2, being only 1.8 million light-years from it. Although it is apparently quite close to NGC 1, the latter is closer and unrelated to NGC 2.
