star cluster
Gravitationally bound suns
A star cluster is a group of stars bound together by gravity, appearing as a concentrated patch of light in the night sky.
Astronomers distinguish between open clusters—loose groupings of hundreds of young stars—and globular clusters, which are dense, ancient spheres containing hundreds of thousands of stars.
The Pleiades is the most famous star cluster visible to the naked eye.
