Messier 37, also known as M37 or NGC 2099, is an open cluster of stars in the constellation Auriga, discovered by the Sicilian astronomer Giovanni Battista Hodierna before 1654 and independently catalogued by Charles Messier in 1764. It is the richest of the three prominent Auriga open clusters catalogued by Messier, holding an estimated 500 or more stars including numerous red giants, and lies roughly 4,500 light-years from Earth.
