Hint: The sun shines because it can convert gravitational energy into light. The sun has a huge mass now we all know that the sun is made up of hydrogen gas. Now due to this tremendous high pressure caused by the mass of the sun the hydrogen gas which is inside gets affected resulting in four atomic nuclei of hydrogen combining into one helium atom.

The splitting of a large, unstable nucleus into two smaller nuclei. During fission: A neutron collides with an unstable nucleus. The neutron and the nucleus are the reactants. The nucleus splits into two smaller nuclei (called daughter nuclei) and two or three neutrons. The daughter nuclei and the neutrons are the products of the reaction
Therefore, this kind of reaction is usually explosive in nature. You may take help from an example of a nuclear fission reaction for better understanding. Uranium is such an element that undergoes nuclear reaction. The energy in the Sun is not because of fission. It is generated in the Sun by the nuclear fusion reaction of hydrogen nuclei into

The specific type of fusion that occurs inside of the Sun is known as proton-proton fusion. Inside the Sun, this process begins with protons (which is simply a lone hydrogen nucleus) and through a series of steps, these protons fuse together and are turned into helium.
So if something strange happened to the fusion reaction in the Sun it would take 50,000 years for us to know about it! Don't worry — the Sun will fuse hydrogen steadily for another 4 billion years. Every second, the Sun converts 4 million tons of hydrogen into energy in its core and radiates it toward its surface!
Inside the Sun, this process begins with protons (which is simply a lone hydrogen nucleus) and through a series of steps, these protons fuse together and are turned into helium. This fusion process occurs inside the core of the Sun, and the transformation results in a release of energy that keeps the sun hot.
