It is believed that as a result of Big Bang this universe came into existence. Our sun is not for ever and it has lived up half of its life. It is around for about 4.5 billion years giving life to our planet earth. The current fuel used by sun is hydrogen which is converted into helium through nuclear fusion emitting huge energy. Half of the hydrogen has already been utilized and the remaining half is sufficient for another 5 billion years. Once the hydrogen is finished, it is expected that sum will start expanding and engulf our earth and other planets. Thereafter it will burn for about a billion years and end-up becoming a white dwarf.

Sun is filled with extremely hot gases.
The temperature at the surface of sun is usually about 5,500 degree centigrade.
The temperature at the core of sun is usually about 15 million degree centigrade.
At the Core of sun, nuclear fusion reactions take place continuously which convert hydrogen into helium resulting in enormous discharge of energy.
The Age of the sun is about 4.5 billion years.
