NGC 5286

Located in the direction of Centaurus and very close in the sky to the naked eye star M Cen, it lies about 35,900 ly from Earth and a roughly similar distance from the galactic centre. Mass is around 7.1x105 solar masses. It is one of the older globular clusters associated with our galaxy, may harbour an intermediate-mass black hole at its centre and is believed to be what remains of a merged dwarf galaxy. 

Classified as V (intermediate concentrations) on the Shapley-Sawyer globular cluster concentration scale (1927).
