Wikipedia on NGC 5474:

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.[3][4] Among the Pinwheel Galaxy's companions, this galaxy is the closest to the Pinwheel Galaxy itself.[3] The gravitational interaction between NGC 5474 and the Pinwheel Galaxy have strongly distorted the galaxy. As a result, the disk is offset relative to the nucleus.[3][5] The star formation in this galaxy (as traced by hydrogen spectral line emission) is also offset from the nucleus.[5] NGC 5474 shows some signs of a spiral structure. As a result, this galaxy is often classified as a dwarf spiral galaxy, a relative rare group of dwarf galaxies.
