Messier 69 or M69, also known NGC 6637, and NGC 6634,[1][2] is a globular cluster in the southern constellation of Sagittarius.Template:Efn It can be found 2.5° to the northeast of the star Epsilon Sagittarii and is dimly visible in 50 mm aperture binoculars. The cluster was discovered by Charles Messier on August 31, 1780, the same night he discovered M70. At the time, he was searching for an object described by Nicolas-Louis de Lacaille in 1751–2 and thought he had rediscovered it, but it is unclear if Lacaille actually described M69.[3]
This cluster is about 28,700[4] light-years away from Earth and Script error: No such module "convert". from the Galactic Center,[5] with a spatial radius of 45 light-years.[6] It is a relatively metal-rich globular cluster that is a likely member of the galactic bulge population.[7] It has a mass of Script error: No such module "val". with a half-mass radius of Script error: No such module "convert".,[8] a core radius of Script error: No such module "convert"., and a tidal radius of Script error: No such module "convert"..[4] Its center has a bright luminosity density of Script error: No such module "val".·pc−3 (meaning per cubic parsec).[5] It is a close neighbor of its analog M70 – possibly only 1,800 light-years separates the two.[9]
