Messier 56 is a globular cluster of stars in the constellation of Lyra. It was discovered in 1779 by Charles Messier.
Spanning 84 light-years in diameter and approx 32,900 light years away it is believed to be about 13.7 billion years old, It is believed to contain around 80,000 stars. A globular cluster is a spherical collection of stars that orbits a galactic core as as satellite. Globular clusters are very tightly bound by gravity, which gives them their spherical shapes and relatively high stellar densities toward their centres. |
