Caldwell 30, also known as NGC 7331, is a spiral galaxy in the constellation Pegasus, discovered by William Herschel in 1784. It lies roughly 40 to 45 million light-years from Earth and is often compared to the Milky Way in overall size and structure; a small group of more distant background galaxies appearing near it in the sky has been nicknamed the Fleas.
