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 core is the source of the Sun’s energy, the site of thermonuclear fusion. At a temperature of about 15, 000, 000 K, matter is in the state known as a plasma: atomic nuclei (principally protons) and electrons moving at very high speeds.

Detailed explanation-3: -Intense heat and pressure in the Sun’s core cause protons to fuse together to form helium atoms, a process that releases large amounts of energy. This nuclear reaction-the same process that takes place in a hydrogen bomb-has powered the Sun for more than 4 billion years.

Detailed explanation-4: -Fusion occurs when two atoms slam together to form a heavier atom, like when two hydrogen atoms fuse to form one helium atom. This is the same process that powers the sun and creates huge amounts of energy-several times greater than fission.

Detailed explanation-5: -The nuclear fusion reactions taking place inside the Sun produce solar energy.
