Although diamond is the hardest substance on Earth, when heated to 763ºC (1404ºF) it vanishes. A bit of CO2 is released, but not even ash remains.
By weight, the sun is 70% hydrogen, 28% helium, 1.5% carbon, nitrogen, and oxygen, and 0.5% all other elements.
It takes eight and a half minutes for light to get from the sun to earth.
