A system of billions of stars held together by gravity is called a galaxy. The one we live in is called the Milky Way galaxy.
An island comprising billions of stars and nebulae, held together by gravity.
Billions of stars make up galaxies. Galaxies are vast systems of stars, planets, gas, and dust that are held together by gravity. Our Milky Way galaxy, for example, consists of billions of stars including our Sun.
A loose grouping of a few thousand stars is called an open star cluster. These clusters typically contain young stars that formed together from the same molecular cloud. Open star clusters are held together by gravity and can be disrupted over time by interactions with other objects in space.
Galaxies, such as the Milky Way and Andromeda, are sources of light that have been found to be collections of billions of stars rather than individual stars. These galaxies contain vast numbers of stars, dust, and gas held together by gravity.

Galaxies are made up of billions of stars, along with gas, dust, and dark matter. These components come together to form vast systems that are bound together by gravity.
Depending on size, that's probably either a globular star cluster (a vaguely spherical grouping of tens of thousands of stars within a galaxy), or a galaxy (an elliptical, disc-shaped or irregular grouping of billions of stars - including several globular clusters).

A galaxy is a big assembly of stars, gas, and dust that is held together by gravity. They come in different shapes and sizes and contain billions to trillions of stars. Our own galaxy is called the Milky Way.
