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 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-3: -The sun not only has a much larger radius than Earth-it is also much more massive. The sun’s mass is more than 333, 000 times that of Earth, and contains about 99.8 percent of all of the mass in the entire solar system! The sun is made up of a blazing combination of gases. These gases are actually in the form of plasma.
