Messier 93 is a star cluster (also catalogued as NGC 2447) in Puppis — a gravitationally bound family of stars sharing a common origin. It was recorded by Charles Messier in his famous catalogue of 110 deep-sky objects. It spans roughly 15 arc-minutes on the sky. At about magnitude 6.2, it is an easy target for binoculars and small telescopes.
Although it appears about 15′ wide on the sky, its real span is roughly 15.7 light-years — the difference is a measure of how far away it lies.
