Messier 38

M38 is an open cluster in the constellation Auriga. Of intermediate age (about 200 million years) and somewhat over 4000 light-years away, M38 lies close to M36 and M37 on the sky and was discovered by several people before Messier added it to his list.

This cluster is kind of a mixture of the properties of the other two clusters. It's a little larger than the others, but consists mainly of fainter stars, similar in magnitude to those of M37. Also similar to M37 is the fact that there is a fairly bright central star, the the cluster is roughly circuler in shape. The cluster is similar to M36, however, in the fact that it's fairly open, and has relatively few stars.
