NGC 6316 is a
Shapley-Sawyer Concentration Class is III, meaning that it has a "strong inner core of stars" and was discovered by the German-born British astronomer William Herschel on 24 May 1784.[5] It is at a distance of about 37,000 light years away from the Earth.[3] NGC 6316 has a metallicity of -0.45;[4] this means that its ratio of hydrogen/helium to other elements is only 35% that of the Sun, but still enough to be considered a "metal-rich" globular cluster.[6]
