Messier 62
Messier 62 is a globular cluster located in the constellation Ophiuchus. It is approximately 22,500 light-years away from Earth and contains hundreds of thousands of stars, tightly packed together due to their strong gravitational attraction. This cluster is one of the more luminous globular clusters, with an apparent magnitude of about 6.5.
Discovered by Charles Messier in 1771, Messier 62 is classified as a type II globular cluster, indicating a high concentration of stars in its core. It is also notable for its population of variable stars, including several RR Lyrae stars, which are used by astronomers to measure distances in the universe.
