Messier 48 is a star cluster (also catalogued as NGC 2548) in Hydra — 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 28.2 arc-minutes on the sky. At about magnitude 5.8, it is an easy target for binoculars and small telescopes.
Although it appears about 28.2′ wide on the sky, its real span is roughly 12.3 light-years — the difference is a measure of how far away it lies.
