M33 is the third largest member of the Local Group of Galaxies after the Andromeda Galaxy (M31) and our own Milky Way.  Estimates state that M33 is 50,000 light-years in diamter; about half that of the Milky Way.  It is the second closest major galaxy to us after M31.  Two popular names for M33 are the Pinwheel Galaxy and the Triangulum Galaxy.  I prefer the later, since M101 is also referred to as the Pinwheel Galaxy.
