NGC 5426 is a spiral galaxy of Hubble type SA (s) c in the constellation Virgo the northern sky , an estimated 113 million light-years from the Milky Way 's center. It forms the interacting galaxy pair Arp 271 with NGC 5427 . The two systems have come so close that the mutual forces of attraction ensure an exchange of materials between the galaxies.
Halton Arp organized his catalog of unusual galaxies into groups according to purely morphological criteria. This pair of galaxies belongs to the class double galaxies with linked arms .
The object was discovered on March 5, 1785 by the German-British astronomer Friedrich Wilhelm Herschel .
