Globular Clusters

<p>Messier 22 is a huge globular star cluster residing at only 10,600 light years distant, making M22 one of the closer globular clusters to Earth. An elliptical globular cluster, M22 is near 100 light years in diameter.

A globular cluster is a spherical collection of stars that orbits a galactic core as a satellite. Globular clusters are very tightly bound by gravity, which gives them their spherical shapes and relatively high stellar densities toward their centers.
