Some facts about Sun

                                 Some facts about Sun

We all know that because of Sun, we get light and heat. But how it comes?
In universe, Hydrogen is the element which is vastly found. Similarly , in Sun too there is a very large amount of Hydrogen. In Sun nuclear fusion reaction takes place. In this reaction, 4 molecules of Hydrogen combine to form an atom of Helium.
In this reaction, a large amount of light and heat are produced as by products. The nuclear fusion reaction is opposite to nuclear fission reaction which is mainly used in making of nuclear bombs.
