~ The Sun is a star – it is not a planet. Our Sun is just like the stars we see in the night sky. The Sun is also the only star we see during the daytime.
~ The Sun is so big that you could fit more than 1 million earths inside of it! It measures more than a million kilometers across.
~ The Sun’s center is about 15 million degrees Celsius. The Sun is so hot that planets millions of kilometers away can feel its heat… That’s mighty hot!
~ The Sun is about 75% hydrogen and 25% helium. This changes slowly over time as the Sun converts hydrogen to helium in its core (center).
~ The Sun’s energy is produced by nuclear fusion reactions. It generates 386 billion billion megawatts of energy!
