Think of a sphere with many a star-
Don't think "galaxy"; that's just too far.
Instead think of stars of the same age
Though in life at a different stage.
Don't confuse my younger cousins with me-
They live elsewhere in the Galaxy.
With some aid, see my fuzzy luster,
For I am a !

For it is a Globular Cluster

Explanation:

These Globular clusters are not considered to be a galaxies because they bond gravitationally to orbiting galaxies like the Milky Way and their masses are relatively small.

In globular clusters, the stars are closed together and they are like 70times closer to one another in their solar neighbourhood.

A globular cluster is a spherical collection of stars that orbits a galactic core. Globular clusters are very tightly bound by gravity, which gives them their spherical shapes, and relatively high stellar densities toward their centers.
