What are some sun facts

My favorite facts are listed in this fun song: "The sun is a mass of incandescent gas, a gigantic nuclear furnace, where hydrogen is built into helium at a temperature of millions of degrees. The sun is hot, the sun is not a place where we could live, but here on earth there'd be no life without the light it gives ... "

Or, you could use these:

The sun actually isn't the largest star in our galaxy, but it's the closest to our planet.

It is made up of hydrogen and helium.

Since the sun is round, it affects the planets by making them go in an oval shaped pattern. Without the gravity of the sun, all planets would move in a straight line.
