NGC 2874 is a barred spiral galaxy of the Hubble type SBbc in the constellation Leo on the ecliptic . It is an estimated 164 million light years away from the Milky Way and has a diameter of around 110,000 ly. Together with NGC 2872, it forms the interacting galaxy pair Arp 307 .
Halton Arp organized his catalog of unusual galaxies into groups according to purely morphological criteria. This pair of galaxies belongs to the class Unclassified double galaxies .
The object was discovered on March 15, 1784 by the German-British astronomer William Herschel .
The northeast arm of the galaxy received its own entry in the NGC catalog ( NGC 2875 ), which was observed by Lawrence Parsons on March 7, 1874 .
