Messier 70 or M70, also known as NGC 6681, is a globular cluster of stars to be found in the south of Sagittarius.Template:Efn It was discovered by Charles Messier in 1780.Template:Efn[1] The famous comet Hale–Bopp was discovered near this cluster in 1995.[2]Template:Efn
It is about 29,400[3] light years away from Earth and around Script error: No such module "convert".[4] from the Galactic Center. It is roughly the same size and luminosity as its neighbour in space, M69.[5] M70 has a very small core radius of Script error: No such module "convert".[6] and a half-light radius of Script error: No such module "convert"..[7] This cluster has undergone core collapse, leaving it centrally concentrated[8] with the luminosity distribution following a power law.[4]
There are two distinct stellar populations in the cluster, with each displaying unique abundances. These likely represent different generations of stars.[9] Five known variable stars lie within its broadest radius, the tidal radius, all of which are RR Lyrae variables.[10][11] The cluster may have two blue stragglers near the core.[4]
