Located in the direction of Libra, it lies about 24,000 ly from Earth and is around 170 ly in diameter. It is one of the few deep sky objects accessible to small telescopes to be found within the bounds of this constellation.
Classified as XI (very loose towards the centre) on the Shapley-Sawyer globular cluster concentration scale (1927), it is clear from the image that the classification is justified.
