sun is a ball of gas. what happens when all the gas has been burnt!?

Question

since sun is continously exhausting the gas of its own by huge burning what happens in the near future

Answer 1

The sun isn't really "burning" the gas, its converting hydrogen to helium in a nuclear fusion reaction. Anyways, eventually, the energy output will reduce and the sun will cool and expand to what is called a red giant. It will become less bright.

When it expands, it is the outer layer expanding while the core is contracting. Then we arrive at crossroads.

In the Sun's case, the outer layers will drift off into space. The Sun will then cool down and become what is called a white dwarf. It will only be a few thousand miles across! There will be no nuclear reactions and it will just glow from heat. Eventually it will lose this heat and become dark, a black dwarf.

In the case of larger stars, if they are large enough, there is a possibility that they will supernova and then collapse into a black hole.

Currently, our Sun is 4.5 billion years old and has used up about 1/2 its fuel. It still has about 5 billion more years until it burns out.

Answer 2

While the Sun is a "ball of gas", it isn't actually "burning". The heat (and light) it produces is due to a process called nuclear fusion, in which hydrogen nuclei are "fused" together to form helium. This is a very exergonic reaction, meaning it releases a lot of energy.

The Sun will eventually run out of hydrogen to fuse, and will start fusing helium into other elements. But don't worry! The Sun still is made up of around 74% hydrogen, so it'll continue to work for a long while yet!

Answer 3

yes sun is a ball of hydrogen and helium gas. the two hydrogen atoms fuse to make helium atom. this reaction is happening for the past about 500 million years and the astronomers said that the hydrogen gas will completely burn out in about 500 million more years. but when this happens this world will endup. means a explosion will be caused by this stopping of this reaction and solar system will blast away in space.

Answer 4

In the immediate future, nothing. It'll take over 10 million years before the sun burns enough of it's own gases to go supernova (explode).

Answer 5

because it truly is a celeb, and stars are, by using definition, balls of burning gasses. specially hydrogen and Helium, i experience. The gasses undergo 3 type of nuclear reaction aspect--it is in reality a large explosion it fairly is so huge it takes billions of years to be complete and is contained right into a ball by using the gravity of its own mass.

Answer 6

I think when something burns it gives out another gas.That's why it won't run out of gas ever.

Answer 7

disappearance of sun energy

Answer 8

well me dont know. Ask sun he will able to tell ya.

Answer 9

We all die. But it will never happen in our life times or our childrens. So don't worry about it.

Answer 10

Darkness, or, imminent death.
