SOLAR SYSTEM

Detailed explanation-1: -Solar energy is created by nuclear fusion that takes place in the sun. Fusion occurs when protons of hydrogen atoms violently collide in the sun’s core and fuse to create a helium atom. This process, known as a PP (proton-proton) chain reaction, emits an enormous amount of energy.

Detailed explanation-2: -The temperature in the Sun’s core is about 27 million degrees Fahrenheit (15 million degrees Celsius) – hot enough to sustain nuclear fusion. This creates outward pressure that supports the star’s gigantic mass, keeping it from collapsing.

Detailed explanation-3: -Radiation from the Sun The sun gets its energy from the process of nuclear fusion. This process occurs in the sun’s core or interior, where temperature and pressure are extremely high. During most of the sun’s life, energy comes from the fusion of hydrogen nuclei.

Detailed explanation-4: –The proton-proton fusion reaction which occurs in the core of the sun at a temperature of about 15, 000, 000 K. In this reaction 0.7% of the total mass disappears and is released as energy.
