Messier 50 (also known as M 50 or NGC 2323) is an open cluster in the constellation Monoceros. It was perhaps discovered by G. D. Cassini before 1711 and independently discovered by Charles Messier in 1772. M50 is at a distance of about 3,000 light-years away from Earth. It is described as a 'heart-shaped' figure.
