A model showing the relative size of the globular star cluster Messier 80. AMNH/D. Finnin

If the Hayden Sphere is the size of the Milky Way Galaxy, then this model is the relative size of the globular star cluster Messier 80.

The globular cluster Messier 80 is a collection of tens of thousands of stars, bound together by their mutual gravity. The Milky Way Galaxy contains about two hundred globular clusters.
