The Andromeda galaxy (M31) is our nearest large galactic neighbor at 2.5 million light years away. The moon, our nearest natural celestial neighbor of any kind, is a mere one light second away. Yet even with it great distance from us, M31 is larger on the sky than the moon! The composite image, taken with the same telescope and camera, shows the approximate difference in angular size between the moon and M31. As time passes over the eons M31 will grow in size as we near each other in a future galactic collision.
