Fun Sun Facts

kids sunWe see the sun (almost) every day, and enjoy its warmth in the summer. But we bet there are some things about the sun you didn’t know — until now.

What is the sun?

The sun is a star. It’s the closest star to earth.

Why does the sun glow?

The sun is made up of electrically charged gasses. Hydrogen gas is turned into helium in the sun’s core, and when lighter elements are forced together to become heavier elements, that’s nuclear fusion. This gives off a tremendous amount of energy.

How hot is the sun?

The sun is about 27 million degrees Fahrenheit at its center. As a reference, people around here would say it’s a hot day if the thermometer reaches 100 degrees.

 

Is the sun following me everywhere I go?

No! It’s an optical illusion. The sun is more than 92 million miles away from us and is so high in the sky that you can see it wherever you go (until it sets, that is).

 

Wait. Does that mean the sun really sets?

No, it doesn’t. It’s just a term we use. The sun stays in its position at the center of our solar system. It only appears to set (and rise) because of the earth’s rotation on its axis.

 

How long does it take for the sun’s heat to reach earth?

About eight minutes.

 

How much would I weigh on the sun?

Say you weigh 85 pounds here on earth.  If you successfully traveled to the sun, you’d weigh more than a ton. To be exact, you’d weigh 2,301.1 pounds.
