NGC 5474 is a peculiar dwarf galaxy in the constellation Ursa Major. It is one of several companion galaxies of the Pinwheel Galaxy (M101), a grand-design spiral galaxy.[4][5]
Among the Pinwheel Galaxy's companions, this galaxy is the closest to the Pinwheel Galaxy itself.[4] The gravitational interaction between NGC 5474 and the Pinwheel Galaxy has strongly distorted the former. As a result, the disk is offset relative to the nucleus.[4][6] The star formation in this galaxy (as traced by hydrogen spectral line emission) is also offset from the nucleus.[6] NGC 5474 shows some signs of a spiral structure. As a result, this galaxy is often classified as a dwarf spiral galaxy, a relatively rare group of dwarf galaxies.
