M62 Located in the direction of Ophiuchus, it is roughly 21,500 ly distant and about 100 ly across. Having a mass of about 1.2x106 solar masses, it is among the ten most massive and luminous globular clusters in our galaxy. Relatively metal-poor (ie contains few elements heavier than helium), its metals abundance is suggestive of two phases of star formation. Classified, IV (intermediate rich concentrations), on the Shapley-Sawyer globular cluster concentration scale (1927).
