NotesThis dwarf elliptical galaxy is thought to have been captured by the gravity of the much larger Andromeda Galaxy, and is now one of many smaller galaxies that follow an orbit around the massive Andromeda spiral.

The last item in the Messier Catalogue was not in fact included by Charles Messier himself, but is one of seven objects added posthumously. It is one of the Andromeda Galaxy's pair of major satellite galaxies (the other, M32, was catalogued by Messier himself). It is a narrowed Ellipse in form, classified as E5 or E6 on the Hubble system.
