The Sun is a yellow dwarf star. It is a hot glowing ball of hydrogen (70%) and helium (28%) at the center of our solar system.Eveen though light is the fastest precieved thing in the universe, it takes light from the Sun eight minutes to reach Earth.A hollow Sun would fit around 960,000 spherical Earths. If squished inside with no wasted space, then around 1,300,000 would fit inside. The Sun’s surface area is 11,990 times that of the Earth’s..Many ancient civilizations thought The Sun was a God.The Sun has a very strong magnetic field. Magnetic energy released by the Sun during magnetic storms causes solar flares. We see these as sunspots. In sunspots, the magnetic lines twist and they spin, much like a tornado would on Earth.
