Messier 102 (also known as M102 or the Spindle Galaxy) is a galaxy listed in the Messier Catalogue that has not been identified unambiguously. Its original discoverer Pierre Méchain later said that it was a duplicate observation of Messier 101, but more recent historical evidence favors that it is NGC 5866,[ although other galaxies have been suggested as possible identities.
