M80

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).
