This massive ball of stars is in the constellation of Centaurus and is the finest example of a
Globular Star Cluster in the sky. With a mass of 5 Million times that of our Sun and at a distance
of just 16000 light years from Earth, it is the largest and one of the closest of the more than one
hundred and fifty globular clusters associated with our Milky Way galaxy. There are several million
stars in this cluster.
