Messier 41 is a star cluster (also catalogued as NGC 2287) in Canis Major — 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 12 arc-minutes on the sky. At about magnitude 4.5, it is bright enough to glimpse with the unaided eye under a dark sky.
Although it appears about 12′ wide on the sky, its real span is roughly 8 light-years — the difference is a measure of how far away it lies.
Observing Messier 41
Messier 41 lies in the constellation Canis Major and is best placed in the evening sky around December. Its maximum altitude above the horizon depends on your latitude. It is best placed for observers in the southern hemisphere, and sits low for those far north. At its brightness it can be found with the unaided eye under a dark sky and is easy in binoculars.
