SOLAR SYSTEM

Detailed explanation-1: -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. During the process some of the mass is converted into energy.

Detailed explanation-2: -Fusion reactions occur when two nuclei come together to form one atom. The reaction that happens in the sun fuses two Hydrogen atoms together to produce Helium. It looks like this in a very simplified way: H + H → He + ENERGY.

Detailed explanation-3: -A fusion reactor produces helium, which is an inert gas. It also produces and consumes tritium within the plant in a closed circuit. Tritium is radioactive (a beta emitter) but its half life is short. It is only used in low amounts so, unlike long-lived radioactive nuclei, it cannot produce any serious danger.

Detailed explanation-4: -The sheer mass of the Sun crushes the atoms of hydrogen within it under gravity, forcing the pressure and temperature up to the point where the nuclei of hydrogen atoms fuse together. A chain of nuclear reactions then takes place, creating nuclei of the next heaviest chemical element, helium.

Detailed explanation-5: -The Sun will expand to a red giant which fuses helium to carbon and oxygen in its core by the Triple Alpha Process. After the helium in its core is used up, the Sun will shed its atmosphere and in the process create a Planetary Nebulae.

Detailed explanation-6: -Two helium-3 nuclei fuse together, producing helium-4, two protons (hydrogen-1), and energy, Helium-3 fuses with helium-4, producing beryllium-7, which decays and then fuses with another proton (hydrogen-1) to yield two helium-4 nuclei plus energy.
