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: -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-3: -Stars are huge celestial bodies made mostly of hydrogen and helium that produce light and heat from the churning nuclear forges inside their cores. Aside from our sun, the dots of light we see in the sky are all light-years from Earth.
