M15 - Pegasus Cluster
The Pegasus Cluster (M15) is a globular cluster located in the constellation Pegasus. It was discovered by Jean-Dominique Maraldi in 1746 and included in Messier's catalog in 1764. M15 is one of the most densely packed globular clusters known.
M15 spans about 175 light-years across and contains over 100,000 stars. The cluster is approximately 33,600 light-years away from Earth and has an apparent magnitude of 6.2, making it visible with binoculars or a small telescope.
