M37 - Open Cluster
M37 is an open cluster located in the constellation Auriga. It was discovered by Giovanni Battista Hodierna before 1654 and independently by Charles Messier in 1764. The cluster is the richest and brightest of the three open clusters in Auriga (M36, M37, and M38).
M37 spans about 20 light-years across and contains around 500 stars. The cluster is approximately 4,500 light-years away from Earth and has an apparent magnitude of 6.2, making it visible with binoculars or a small telescope.
