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 was discovered by German-British astronomer William Herschel on 12 March 1785. [3] It spans 62,000 light-years, approximately 60% of the Milky Way's diameter. 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 superimposed star". [4] NGC 2608 is now thought to be a pair of interacting galaxies. [5]
