Spiral galaxy NGC 7331, also known as the Caldwell 30, is pretty similar to our Milky Way in terms of mass, size and shape. Located in the constellation Pegasus, Caldwell 30 is about 45 million lightyears away from us. The galaxy got the nickname Caldwell 30 because it is a member of the group of 86 objects catalogued by astronomer Sir Patrick Moore. He named the objects the Caldwell Objects because his full surname is actually Caldwell-Moore.
