Description

The Pinwheel Galaxy sits about 21 million light years from earth in the constellation Ursa Major. If you can find the big dipper, moving away from the bowl down the handle, the first star you come to is Alioth and the second is Mizar. If you continue on an imaginary line in this direction (don't make the turn in the handle) for about the same distance that you travelled from Alioth, then you are in the area of M101. It is classified as a spiral galaxy - pretty easy to see why
