in  Sagittarius

It was one of the first globular clusters to be discovered (1665 or even earlier) and is located about 10,000 light years from Earth, one of the closest globulars. With a luminosity of 210,000 stars and visual magnitude of 5.1, it is one of the most easily visualized globulars in the northern sky.
