M56 is located about half-way between Beta Cygni (Albireo) and Gamma Lyrae. It is one of the less bright globulars, especially lacking the bright core which most globulars have. Nevertheless it is not too difficult to resolve, even at its rather large distance. Its diameter is near 60 light years. This stellar swarm is approaching us at the high velocity of 145 km/sec. Only about a dozen of variables were identified in M56.
