Messier Object 13, the Great Globular Cluster in Hercules; one of the most prominent and best known globular clusters of the Northern celestial hemisphere.

The Great Globular Cluster in Hercules (also known as the Hercules Globular Cluster, Messier Object 13, Messier 13, M13, or NGC 6205) is a globular cluster in the Hercules constellation at right ascension 16h 41.7m and declination +36° 28'.

With an apparent magnitude of 5.8, it is barely visible with the naked eye on a very clear night. Its real diameter is about 165 light years, and is composed of several hundred thousand stars. It is almost 35,000 light-years away from Earth.

Globular clusterA globular cluster is a spherical bundle of stars that orbits a galaxy as a satellite. Globular clusters are very tightly gravitationally bound, which gives them their spherical shape, and extremely dense (in relative terms) towards their core.

This distinguishes them from fibrous proteins, such as keratin, which may not as soluble.
