NGC 2608 = Arp 12 is a merging bar-spiral galaxy of the Hubble type SBb in the constellation Cancer on the ecliptic . It is estimated to be 93 million light-years away from the Milky Way and has a diameter of about 50,000 ly. In the same area of ​​the sky there is u. a. the galaxy NGC 2619 .

The supernovae SN 1920A (Type-I) and SN 2001bg ( Type-Ia ) were observed here.

Halton Arp organized his catalog of unusual galaxies into groups according to purely morphological criteria. This galaxy belongs to the class spiral galaxies with split arms (Arp catalog) .

The object was discovered by Wilhelm Herschel on March 12, 1785 .
