The Earth, the Moon, and the Sun
How do the Sun and the Moon affect the Earth? Without the Sun, the Earth would be a big ball of frozen mud, just another asteroid, drifting in space with no gravity to anchor it here and nothing to give us heat and light. We could not be here without the Sun.
The Moon is another story. The Moon could not be here without the Earth. Most scientists now believe that the Moon was ripped from the Earth by a massive impact billions of years ago. Our Moon is very much like our Earth-- except that it has no atmosphere. There may be some water frozen at the poles, left over from an earlier time. There also seem to have been volcanoes there once. You can find old lava flows on the Moon. Just look for the dark spots.
What happens on the Sun and the Moon can change what we see and feel here on Earth. Solar flares can mess up TV and radio, and the Moon's gravity affects the tides. How will we affect the Moon? We have visited the Moon, and sometime in the future, there could be a Moon colony. Scientists are already working out the details for that.

What's So Special about Planet Earth? Wells, Robert E.
"Move to another planet? Sounds interesting! In our imaginary spaceship, let's check out the planets in our solar system. Mercury is closest, but it has no air, and it's either sizzling hot or bitterly cold. The atmosphere on Venus is poisonous; plus, human beings would cook there. Mars might work, but you'd always have to be in a protective shelter. And if you got to the outer planets, you couldn't even land as they are mostly made of gas! Our home planet is looking good. Why is Earth so comfortable for plants, animals, and people? As Robert E. Wells explains, it's because of our just-right position form the sun, marvelous atmosphere, and abundant water. Our planet is very special and perfect for us, and that's why we must do all we can to keep Earth healthy."
