NGC 6342 is a globular cluster located in the constellation Ophiuchus. Its Shapley–Sawyer Concentration Class is IV, [1] and it was discovered by the German-born British astronomer William Herschel on 28 May 1786. [4] It is at a distance of 28,000 light years away from Earth. [5] [6]

NGC 6342 is classified as metal-rich, yet has only one generation of stars. [3]
