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 the only star in our solar system. It is the center of our solar system, and its gravity holds the solar system together. Everything in our solar system revolves around it – the planets, asteroids, comets, and tiny bits of space debris.
Detailed explanation-3: -Stars are giant balls of hot gases that can produce their own light. Stars give out energy by converting Hydrogen gas into Helium in their cores. Stars are gigantic in size and have an immense gravitational attraction. The sun is a medium-sized star that gives us energy and makes life possible on earth.
Detailed explanation-4: -The heavenly bodies which radiate heat and light are called stars.
