NGC 6362 is a globular cluster in the constellation Ara, lying close to Apus in the southern sky. A telescope with a 150mm primary mirror is required to resolve the stars within this irregularly shaped cluster. [4] British astronomer James Dunlop first observed the cluster on 30 June 1826. It is located about 25,000 light-years from Earth and contains a number of blue stragglers. [7] [8] [9]
