Long identified as a tightly grouped open star cluster, spectroscopic analysis in the 1970’s showed this group of stars is a loosely grouped globular cluster. It is located in the constellation Sagitta (The Arrow) and is about 13,000 light-years from the Sun. At that distance, the cluster is about 27 light-years in diameter.
