Can a fire burn without oxygen?
A fire cannot burn without oxygen. It should be noted that in the presence of carbon, nitrogen and oxygen, stars heavier than the Sun may burn hydrogen to helium by using the C, N and O as catalysts. Even in these stars, however, an absence of oxygen does not prevent nuclear burning.
What makes the sun keep burning?
The sun, like the rest of the universe, is made mostly of hydrogen. There isn’t enough oxygen in the entire solar system to keep the surface of the sun burning through chemical combustion for more than a very short time—probably hours. Instead, the sun’s heat and light comes from thermonuclear fusion.
