NGC 5566 is a bar-spiral galaxy with an active nucleus of the Hubble type SBab in the constellation Virgo on the ecliptic . It is an estimated 67 million light years from the Milky Way and about 135,000 light years in diameter . Together with the galaxies NGC 5560 and NGC 5569 , it forms a gravitationally interacting trio with catalog no. Arp 286 . Halton Arp organized his catalog of unusual galaxies into groups according to purely morphological criteria. This galaxy pair belongs to the class double galaxies with inflow and attraction .
The object was discovered on April 30, 1786 by the German-British astronomer Wilhelm Herschel .
