NGC 5986 is a globular cluster of stars in the southern constellation of Lupus, located at a distance of approximately Script error: No such module "convert". from the Sun.[1] It was discovered by Scottish astronomer James Dunlop on May 10, 1826. John L. E. Dreyer described it as, "a remarkable object, a globular cluster, very bright, large, round, very gradually brighter middle, stars of 13th to 15th magnitude".[2] Its prograde–retrograde orbit through the Milky Way galaxy is considered irregular and highly eccentric. It has a mean heliocentric radial velocity of +100 km/s.[3] The galacto-centric distance is Script error: No such module "convert"., which puts it in the galaxy's inner halo.[4]
This is relatively massive cluster has been poorly studied, at least as of 2017.[3] It is moderately concentrated, with a core radius of Script error: No such module "val". and a projected half-light radius of Script error: No such module "val".. The three dimensional half-mass radius is Script error: No such module "val"..[5] The cluster has a higher metallicity – what astronomers term the abundance of elements with higher atomic number then helium – compared to most other objects of its type.[6] It may have at least 4–5 different stellar populations with distinct elemental compositions, and there is evidence that it has lost ~60–80% of its original mass.[3]
