Made up of 70 percent hydrogen and about 28 percent helium(plus other gases), the sun is the center of our solar system and the largest celestial body anywhere near us.
Talking about size it is 100 times bigger and weighs over 300,000 times that of Earth.
The surface of the sun is a dense layer of plasma at a temperature of 5,800 degrees Kelvin. At its core, the Sun's temperature and pressure are so high, and hydrogen atoms are moving so fast that it causes fusion, turning hydrogen atoms into helium.
Electromagnetic radiation travels out from the Sun's core to its surface, escaping into space as electromagnetic radiation, blinding light, and incredible levels of solar heat.
