The Sun helps to heat the earth - what is it made out of

Everyone knows the sun is at the center of the solar system, but not many know what the sun is made of. So what is the sun made of?

The sun is made up of plasma. It comprises mostly of hydrogen and helium. Hydrogen, accounts for approximately 74 percent of the total mass of the sun, while helium accounts for 24 percent of the total mass. The other elements that the sun is comprised of are oxygen, iron, silicon, nickel, sulfur, magnesium, neon, carbon, chromium and calcium. Oxygen is 1 percent of the total mass of the sun, while the other elements constitute 1 percent of the total composition of the sun.

So where did these elements come from? The hydrogen and helium came from the Big Bang. The other elements were formed from dying stars. Stars are continuously fusing hydrogen into helium in their cores. As the hydrogen in the core diminishes, the stars start to fuse heavier metals such as oxygen and helium.
