NGC 5257 is a spiral galaxy located in the constellation Virgo. The galaxy is notably interacting with the spiral galaxy NGC 5258. The two galaxies are listed together as Arp 240 in the Atlas of Peculiar Galaxies.[2] Both galaxies are distorted by the gravitational interaction, and both are connected by a tidal bridge, as can be seen in images of these galaxies.
