6101

NGC 6101 (also known as Caldwell 107) is a globular cluster in the constellation Apus, which was discovered by James Dunlop and catalogued by him as Δ68. 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 (7.9 in) aperture to resolve individual stars. Research revealed this cluster to contain an unexpected large number of black holes.
