M56 Globular Star Cluster



M56 is a magnitude 8.4 globular star cluster that is about 8.8 arc-minutes in diameter. This star cluster was discovered by Charles Messier on the same night that he discovered a comet on January 19, 1779. M56 appears fairly uniform without a central condensation when viewed through a telescope, and is not considered to be a very rich cluster. It is about 60 light-years in diameter and about 46,000 light-years away.
