NGC 3310 = Arp 217 is a bar-spiral galaxy of the Hubble type SBbc pec in the constellation Great Bear south of the ecliptic . It is around 47 million light years away from the Milky Way and has a maximum extension of around 41,000 light years .
The object is believed to have collided with and merged with one of their satellite galaxies about 100 million years ago. This collision is the suspected cause of the very strong star formation taking place in it . Halton Arp organized his catalog of unusual galaxies into groups according to purely morphological criteria. This galaxy belongs to the class of galaxies with adjacent loops .
NGC 3310 was discovered on April 12, 1789 by the German-British astronomer Wilhelm Herschel .
