Located in the direction of Scorpius, it is 32,600 ly distant from Earth, approximately 95 ly across and ranks amongst the most densely populated globular clusters of our galaxy. With a mass of about 5.0x105 solar masses, it hosts many so-called "blue-stragglers" - stars that appear younger than expected - but may be stars that have collided or have had their outer layers stripped by close encounters. Classified, II (dense central concentration), on the Shapley-Sawyer globular cluster concentration scale (1927).
