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 earth circles tile sun. It takes one year for the earth to go completely around. The earth spins around once every 24 hours. In the morning the sun seems to rise in the east. As the day goes on, the sun seems to travel across the sky. In the evening the sun seems to set in the west and then it is night. Almost every part of the earth turns from day to night during every 24 hours.
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.
