✦ The Sun is made up of 75% hydrogen, 24% helium and only 1% of other planets. The heavy amount of light gases like hydrogen and helium helps in the energy production by nuclear fusion.

✦ Nuclear fusion means the process in which nucleus of small atoms are converted into large masses which releases a lot of energy. Here, hydrogen is converted into helium and energy is liberated.

✦ The three prominent layers of Sun interior:

• Core(Here, Nuclear fusion takes place)
• Radiative zone
