What a beautiful day!
The sun is shining and everything looks bright. Stand in tile sun. Can you feel the heat of the sun? The sun that gives the heat is very far away. It is hard to believe, but the sun is about one hundred and fifty million kilometers away. If a plane flew day and night without stopping, it would take nearly 18 years to get to the sun.
The sun doesn't seem very big to us, but it's really very huge. One million balls as big as our earth could fit inside the sun. The sun looks small because it is so far away. If the sun were much nearer, our earth would be too hot to live on. If there were no sun, the earth would be so cold that nothing could live on it. Aren't we lucky to be just about the right distance away from the sun?
The sun gives us light. It keeps us warm. It makes things grow. Plants, animals and people need the sun. The sun makes our earth beautiful. We could not live with out the sun.
