There have been a lot of people answering this question and most of them have told you that the process in the sun is fusion and that fusion does not require oxygen.
That is correct.
We use the term "burning" rather loosly when we discuss the sun or any other star for that matter. And we probably should not. Fusion is not really burning anything.
Burning (which DOES require oxygen) is a chemical reaction also called combustion. Burning is the breaking of molecular bonds between atoms in a molecule. You change one chemical compound into another.
Fusion is the combining of atomic nuclei to change one element into another.
On a side note, fission (which someone else mentioned) is the reverse of fusion. It is the division of atomic nuclei to change one element into another.
And in my opinion, it was a good question.

The sun isn't burning. It's fusing Hydrogen atoms together. This takes the amount of heat and pressure that's found in the center of our sun. When two atoms of Hydrogen are fused together to form an atom of Helium, a small portion of the mass is converted in to energy. This energy created gets to us as sunlight.
The sun works the same way a hydrogen bomb works.

properly 3 out of the first 4 solutions were given it: fusion would not require oxygen. in spite of the undeniable fact that, you would possibly want to also question how rockets in area burn because rocket gas does favor oxygen. the answer: they convey about the oxygen with them in liquid style in tanks. purely as a accessible reference, the you may shop in ideas the version between a rocket and a jet is that the rocket brings its own oxygen and ought to hence artwork in area at the same time as a jet needs oxygen from the ambience to artwork (it is why jets have a optimal altitude previously they do no longer have sufficient air to shop the gas burning).

About 74% of the Sun's mass is hydrogen, 25% is helium, and the rest is made up of trace quantities of heavier elements. The Sun is about 4.6 billion years old and is about halfway through its main-sequence evolution, during which nuclear fusion reactions in its core fuse hydrogen into helium. Each second, more than 4 million tonnes of matter are converted into energy within the Sun's core, producing neutrinos and solar RADIATION.

Sun is not burning. actually hydrogen fusion reactions takes place inside sun and thats what keeps the sun radiating all the enrgy.
the energy that causes havouc in form of nuclear bombs also radiates energy because of nuclear fission but here atoms of uranium U-235 disintegrate to radiate energy.
in sun atoms of hydrogen combine or fuse together and release lots of energy thats how the sun radiates energy

is it you or somebody else who poses this question regularly. The Sun burns because of a nuclear reaction which requires no oxygen to sustain it. In this reaction hydrogen is converted to helium which is converted to lithium etc.....

Because the sun isn't burning via combustion. What's happening in the sun is nuclear fusion.

there is no burning in sun there some nuclear action changing
hydrogen to helium
