Do you know where the supply of fuel that keeps sun burning and shining?

Question

The sun existed millions of years. Does anyone knows where the continuous fuel comes from that keeps the sun burning? Can the source of energy that keeps it burning run out?

Answer 1

well first the sun is like a solar panel within itself,meaning by the power it generates doesn't leave for 100000 of years and also it has a core of liquid hot magma which probably will take trillions of years to burn out.

Answer 2

The sun's hydrogen fuel supply comes from the original cloud of gas and dust in which it formed about 4.5-billion years ago. Since then it's been "burning" that fuel at a rate of some 4,629 metric tons per SECOND..! Even at that rate the sun still has enough hydrogen fuel to keep it going without any change for at least another 1.5-billion years. At that point in time it will have exhausted its hydrogen fuel and begin "burning" helium. Finally, in about 4.5-billion years, the sun will end its life as a white dwarf star.

Answer 3

The sun is not burning (its not a fire).



The sun has been fusing hydrogen in its core (called nuclear fusion) at the rate of 4 million tonnes of matter per second.

So over the 4.5 billion years of the sun's life it has converted around 100 Earth-masses of matter into energy.



The sun started with 332,950 times the mass of the Earth - 100 Earth masses is 0.0003% the mass of the sun.



The sun will spend another 4 billion years fusing hydrogen into helium before instabilities cause it to expand into a red giant.

Answer 4

the sun is currently running on hydrogen. yes it can get used up...but this has different outcomes for different sizes of stars. the way stars work is they get their fuel from elements constantly reacting to form new heavier elements (hydrogen forms helium for example) because the reactions release energy. since the sun is average sized it will *eventually* turn into a white dwarf

Answer 5

The fuel is the Hydrogen inside of the star.



Yes it will run out, all stars run out and die (creating white dwarf, black hole, pulsar, etc.) through a Nova or Supernova.



Our sun will become a white dwarf.
