THE SUN
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!
