Detailed explanation-1: -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-2: -Sun-the star of our solar system is a star because it produces energy by the fusion reaction of Helium turning into Hydrogen. Our Sun is an average-sized star: there are smaller stars and larger stars, even up to 100 times larger. The Sun is composed almost entirely of hydrogen and helium gas.
