The Sun is a main-sequence star, and generates its energy by NUCLEAR FUSION of hydrogen nuclei into helium. In its core, the Sun fuses 620 million metric tons of hydrogen each second.
Extremely high temperatures and pressures are needed to spark nuclear fusion, a process in which atomic nuclei — the protons and neutrons of atoms — literally fuse together to create a heavier element. And if the conditions are right, that fusion can release massive amounts of energy.
This reaction is still not feasible on earth.
