The source of energy of the Sun is due to the conversion of hydrogen to helium.
Solar energy is created as a result of a process known as Nuclear Fusion, a chain reaction that takes place in the Sun.
The area that extends from the center of the Sun to a radius of 20-25 % is known as the core. When the protons of the hydrogen atoms collide in the core of the Sun, it is converted into helium atoms. Four hydrogen nuclei combine to form one helium nucleus.
This reaction in which an enormous amount of heat and energy is emitted is known as the P-P reaction or proton-proton reaction.
.It takes place under the condition of extreme pressure and temperature in the core of the Sun.
Solar energy travels to Earth at a speed of 1,86,000 miles per second.
The solar radiation from the Sun includes Ultraviolet rays, X-rays, and gamma rays.
The nuclear fusion in Sun is similar to that of a hydrogen bomb explosion.
