See the answer below...

Explanation:

It is NOT the case that the sun BURNS but here it is a case of nuclear fission and fusion...actually the SUN is a huge storage of HYDROGEN GAS and HELIUM GAS.

The gas molecules join to each other by nuclear fusion and releases a huge amount of energy... the energy is too much that it helps to the SUN to have a temperature of #5505^@C# (approx.) and it burns...

Hope it helps...

Burning is actually a chemical reaction. The Sun produces energy by a fusion reaction, which is also often referred to as burning.

Explanation:

When something burns in air, there is actually a chemical reaction taking place. Oxygen from the air combines with the fuel atoms and molecules to produce oxides. The creation of the oxides creates chemical bonds which liberate energy in the form of heat and light.

The Sun is mainly Hydrogen and some Helium. In the core of the Sun the temperatures are around #15,000,000^@C#. At these temperatures fusion reactions take place which fuse 4 Hydrogen nuclei into a Helium nucleus. This releases a lot of energy. The fusion only takes place in the Sun's core, but the surface temperatures are hot at #6,000^@C#.

So, the Sun produces energy by fusion. As fusion is an energy producing process, it is often referred to as burning. In any context other than the core of a star, burning refers to the chemical reactions which require an oxidant such as oxygen. Chemical burning produces a lot less energy than fusion "burning".
