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: -The stars are known to generate energy through the process of nuclear fusion. This reaction typically converts hydrogen to helium and other heavier elements in the stars. As the name suggests, nuclear fusion reaction involves the elements of the nucleus of an atom.

Detailed explanation-3: -Nuclear energy can be of two types: nuclear fission and nuclear fusion. Both the types is used for the generation of electricity.

Detailed explanation-4: -The energy released due to a loss in mass during the process of nuclear fission and fusion is called nuclear energy.
