What is the closest galaxy to the Pinwheel Galaxy?

Say hello to the much-photographed Triangulum galaxy – aka Messier 33 – a face-on pinwheel of swarming suns and the second-nearest spiral galaxy to our Milky Way. This galaxy is only about 2.7 million light-years away. It’s huge, with a diameter about half that of our Milky Way.

How old is M101?

about 20.9 million years ago
M101 has an apparent visual magnitude of 7.86 and is approximately 20.9 million light years distant from Earth, which means that we are seeing it as it was about 20.9 million years ago. The Pinwheel Galaxy contains hundreds of billions of stars and is notable for its many large, bright star forming regions.
