Detailed explanation-1: -Nuclear Fusion reactions power the Sun and other stars. In a fusion reaction, two light nuclei merge to form a single heavier nucleus. The process releases energy because the total mass of the resulting single nucleus is less than the mass of the two original nuclei. The leftover mass becomes energy.
Detailed explanation-2: -In the core of the Sun hydrogen is being converted into helium. This is called nuclear fusion. It takes four hydrogen atoms to fuse into each helium atom.
Detailed explanation-3: -The Inner Core of the Sun is the main engine of this star. Here, gravity and heat provide the necessary energy to drive the nuclear fusion processes that power the sun. In the core, the fusion processes called the Proton-Proton Cycle and the Carbon-Nitrogen-Oxygen Cycle take place.
Detailed explanation-4: -To fuse in our sun, nuclei need to collide with each other at extremely high temperatures, around ten million degrees Celsius. The high temperature provides them with enough energy to overcome their mutual electrical repulsion.
