It is estimated to be 309 million light years away from the Milky Way and has a diameter of around 275,000 ly. Together with NGC 2830 and NGC 2831 , it forms the galaxy trio Arp 315 . Halton Arp organized his catalog of unusual galaxies into groups according to purely morphological criteria. This galaxy triplet belongs to the class of galaxy groups .
The Type Ia supernova SN 2014ai was observed here.
The object was discovered by Wilhelm Herschel on December 7, 1785 .
