SOLAR SYSTEM

Detailed explanation-1: -Overview: A star is a huge luminous ball of hot gas, mostly hydrogen and helium, held together by gravity. Nuclear reactions in the cores of all stars, including our Sun, produce energy in the form of light. Stars shine because this light works its way to the surface and radiates out into space.

Detailed explanation-2: -The sun is in the center of the solar system. It is huge and made up of extremely hot gases because of which is also called as the big ball of fire. It is mostly composed of hydrogen and helium.

Detailed explanation-3: -Our Sun is a 4.5 billion-year-old star – a hot glowing ball of hydrogen and helium at the center of our solar system. The Sun is about 93 million miles (150 million kilometers) from Earth, and without its energy, life as we know it could not exist here on our home planet.

Detailed explanation-4: -The Sun is a 4.5 billion-year-old yellow dwarf star – a hot glowing ball of hydrogen and helium – at the center of our solar system. It’s about 93 million miles (150 million kilometers) from Earth and it’s our solar system’s only star. Without the Sun’s energy, life as we know it could not exist on our home planet.

Detailed explanation-5: -A star is a glowing ball of very hot gas called plasma born in a huge cloud of hydrogen, known as a stellar nursery, where pockets of gas clump together.

Detailed explanation-6: -Stars produce their energy through nuclear fusion. For most stars, this process is dominated by a process called the “proton-proton chain, ‘’ a sequence of events that transforms four hydrogen atoms into one helium atom.
