It is located at a distance of about 47,600 light-years from the Sun and about 36,500 light-years from the Galactic Center of the Milky Way. It requires a telescope of at least 20 cm aperture to resolve individual stars. Research revealed this cluster to contain an unexpected large number of black holes.
