NGC 2 is a spiral galaxy of Hubble type Sab in the constellation Pegasus at the northern sky . It is estimated to be 345 million light-years from the Milky Way and about 100,000 light-years across. Together with NGC 1 it forms the optical pair of galaxies Holm 2 or KPG 2 , but the former is about twice as far away, so there is no connection between these two galaxies.
In the same area of the sky there are still u. a. the galaxies NGC 16 and NGC 22 .
The object was discovered on August 20, 1873 by the Irish astronomer Lawrence Parsons .
