NGC 2608 (also known as Arp 12) is a barred spiral galaxy located 93 million light-years away in the constellation Cancer (the Crab). It is 62,000 light-years across, and about 60% of the width of the Milky Way. It is considered a grand design spiral galaxy and is classified as SB(s)b, meaning that the galaxy's arms wind moderately (neither tightly nor loosely) around the prominent central bar.
It was classified under "galaxies with split arms" in the 1966 Atlas of Peculiar Galaxies by Halton Arp, who noted that the "nucleus may be double or superposed star".[3] NGC 2608 is now considered to be a pair of interacting galaxies.[4]
