Open Clusters One of the nearest star clusters to us is the Hyades. Here is a fascinating 3D animation which shows the cluster moving through space. Globular ClustersThese can have over one million member stars! One of the most prominent and easily observed globular clusters is the Hercules cluster, M13.
One of the types of objects on Charles Messier’s list for comet hunters is the star cluster. Some clusters can be mistaken for comets in small telescopes. That is why Mesier made his list. Stars can form into very large groupings called star clusters. In our galaxy, we find two distinct types of clusters, Open and Globular.
