M81 (on the right) is a spiral galaxy that forms a pair with the irregular galaxy M82. The distance between the two galaxies is some 150,000 light years. M81 is the largest galaxy within in a group of 34, and is located 12 million light years away from planet Earth. This makes it one of the closet groups to the Local Group, which contains the Milky Way.
