5. It has different layers
Facts about Sun: The first is the photo sphere which has a temperature of 5726 ° C, followed by the convection zone, where the heat moves slowly from the inside to the surface. Then comes the radioactive zone and in the center the core and the temperature of the core of the Sun is ~ 1.36 × 107 K, no less than about 15,600,729 ˚C, according to the Scientific Eye.

At least mainly, if I had a label I would say something like:
2% other basic elements (iron, nickel, oxygen and several others)

10. It is warming more and more| Facts about Sun
Facts about Sun: Every 10 billion years it becomes 10% brighter. Some believe that this will threaten life on our planet to a very, very long term, to the extent that there will come a time when only bacteria can live on the planet.
