Binary bc The Milky Way has about 150 globular clusters. Larger galaxies have more, but still in the 100s or a few thousand. They are found in the halo of a galaxy, contain considerably more stars and are much older than the less dense galactic, or open clusters, which are found in the disk.

There are groups of stars that we describe as "globular" clusters, and there are others described as "open" clusters.

There are no such things as "binary" clusters, "eclipsing" clusters, or "wobbling" clusters.
