COMMENTS:

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.
