SOLAR SYSTEM

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: -Nuclear fusion is the process by which two light atomic nuclei combine to form a single heavier one while releasing massive amounts of energy.

Detailed explanation-4: -Inside the sun, fusion reactions take place at very high temperatures and enormous gravitational pressures. The foundation of nuclear energy is harnessing the power of atoms by splitting apart, a process called fission, or combining them, called fusion.
