Gravity pulls gas particle together. As gravity pulls more and more atoms, closer and closer together they eventually begin to fuse together. Once fusion starts on a large enough scale, at star is born.

∙ 12y agoStars form when gravity pull gases that are just drifting through the universe together. Take, for example, our sun. The sun was formed when a very huge amount of hydrogen and helium gases came together (via gravity) and started interacting (with fission) to produce heat and light. Eventually, the sun will run out of fuel, and it will no longer be able to produce the energy that 1) heats our planet and 2) prevents gravity from imploding the star. When this happens, the sun will likely become a white dwarf (small, relatively dim star), or similar star, (as it is not big enough to produce a nova or black hole, etc.) and we will all perish :)

How does speed and acceleration effect gravity?
Speed or acceleration have no effect on gravity.
How does air effect gravity?
Air has no effect on gravity. But the presence of air can change the response of an object to the force of gravity alone.
What is gravity if it is not a force?
Gravity really is one of the four main forces of the Universe. gravity is an effect and not the cause of anything, no gravitation's, no gravity waves, none of it. gravity is a dynamic effect. the acceleration of the underlying for of energy focused to the center of a mass. there is no separate force called gravity, just a dynamic effect we call 'gravity'
What is the effect of gravity on velocity?
Gravity is a force and any force acting on a body changes its velocity in the direction of the force.
What is masses effect on gravity?
It is masses that cause gravity in the first place.
How does a star stay in the sky?
The stars are too far away of Earth's gravity to have any noticeable effect on them.
How does gravity effect the stars?
Please check the difference between the words "affect" and "effect". In this case, it should be "affect". Gravity keeps the stars together in the first place. It compresses them so much that they become hot and dense in their cores; enough so to start nuclear fusion.
How does gravity effect stellar evolution?
Gravity effects stellar evolution by pulling down force on the stars while they are forming. Mass will determine how long the star stays alive and burning.
Are stars rounded by gravity?
yes because they levitate in space gravity does hold stars up
Do stars twinkle due to refraction or gravity?
Stars in the universe twinkle because of refraction not gravity.
How are stars made with no gravity?
They aren't. Stars form as a result of a cloud of gas collapsing due to gravity.
How does speed and acceleration effect gravity?
Speed or acceleration have no effect on gravity.
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.
Which pulling force do planets and stars have?
Planets and stars have gravity.
How acceleration effect gravity?
Acceleration does not effect gravity. It is rather the other way round. Gravity can affect the rate of acceleration.
How does air effect gravity?
Air has no effect on gravity. But the presence of air can change the response of an object to the force of gravity alone.
What force is responsible for holding the stars gases and dust together in a galaxy?
The answer is simple: gravity.
