How does the sun stay on fire?

The sun is not on fire…………..There is no oxygen there for no fire and flame. The sun is made up of a heap of hydrogen and helium gas that stays in one spot because in space there is nothing but planets, stars and meteors. Both the gases combined make the sun nuclear!
The nuclear power makes sun hotter than everything except lightning, any contact with the sun, even the slightest, will result in instant death.

109 earths can fit into the sun.
Its outer, visible layer is 6000 degrees Celsius while the inner layer is 15000000 degrees Celsius.
