That is a galaxy.

The collection of stars held together by the force of gravity is called a galaxy. Galaxies can vary in size and shape, and they contain not only stars but also gas, dust, and dark matter. Our own galaxy is known as the Milky Way.
No, a nebula is not a galaxy. A nebula is a cloud of gas and dust in space, while a galaxy is a collection of stars, gas, dust, and dark matter held together by gravity. Galaxies can contain nebulae, among other structures.
A vast collection of stars is called a galaxy. Galaxies are massive systems that contain stars, planets, gas, dust, and dark matter, held together by gravity. The Milky Way is an example of a galaxy that contains our solar system.
A very large system of stars held together by gravity is called a galaxy. Galaxies can contain billions to trillions of stars, along with gas, dust, and dark matter. They come in various shapes, such as spiral, elliptical, and irregular. Our own Milky Way is an example of a spiral galaxy.
If they form a galaxy, it's called a galaxy of course.

Gravity
The answer is simple: gravity.
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.
