What is the system of billions or stars held together by 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.
How does gravity affect the stars moon an planets?
Gravity keeps the planets in orbit around the sun and the stars and the stars in orbit around the center of the galaxy. Gravity also holds the stars together against their own internal pressure.
What are stars in the sky held together by?
Stars in the sky are held together by gravity. Gravity is the force that pulls all the mass of a star together, preventing it from expanding outward. It is this balance of internal pressure from nuclear reactions and gravitational forces that keeps a star stable.
What is a galaxy and what force holds it together?
An island comprising billions of stars and nebulae, held together by gravity.
What force holds matter of nebula together?
Gravity is the force that holds matter in a nebula together. As the nebula contracts under its own gravity, the particles begin to clump together, eventually forming stars and other celestial bodies.
What holds the planet and stars together?

What is gravity's job in the universe?
Gravity basically makes things come together, and keep together. For example, due to gravity: * Galaxies form and keep together * Stars form and keep together * Stars get hot enough for nuclear fusion to start * Planets form and keep together * Planets keep around their stars, instead of wandering off into space
How does gravity affect the stars moon an planets?
Gravity keeps the planets in orbit around the sun and the stars and the stars in orbit around the center of the galaxy. Gravity also holds the stars together against their own internal pressure.
How do stars retain there shape?
Their own gravity keeps them together.
What is a system of billions of stars held together by gravity?

What else are stars made up of?
stars are massive luminous ball of plasma that is held together by gravity
What are huge balls of gas that are held together by gravity and give off their own light?
