Unusually large globular cluster in Centaurus, target for several long range missions.

This cluster is 150 light years in diameter, about 15,800 light years away and contains about 6 million stars. This unusual cluster is known by Terragen astronomers to be the remains of a disrupted minor galaxy which is orbiting the Milky Way closely, periodically passing through the galactic plane.
