Description
Sb type of galaxy located in Ursa Major . It is a conspicuous spiral galaxy since it shines bright (6.9 Mag) and is large (21 X 10 arc min.) . Reportedly has been seen with the unaided eye under extremely clear transparent skies. It's 12,000,000 ly away so it's fairly close and in our local group. M 81 was discovered by Johann Elert Bode in 1774. He also named Uranus. You can Google him and read more about him. It is estimated that M 81 has just over 200 globular clusters associated with it.
