M 15 NGC 7078 Pegasus Cluster is a globular cluster in the constellation Pegasus and is about 35,700 light-years from Earth, and 175 light-years in diameter. At an estimated 12.5±1.3 billion years old, it is one of the oldest known globular clusters. Messier 15 is one of the densest globular clusters known, with most of its mass concentrated at its core. The cluster contains more than 100,000 stars, including a considerable number of variables (112) and pulsars (8). It has an absolute magnitude of -9.2, which makes it about 360,000 times more luminous than the Sun. Approaching naked eye visibility under excellent conditions, M15 is easily seen with binoculars or finder scopes appearing as a fuzzy star. Apparent magnitude 6.2.
