Since Astronomy was one of my favorite subjects when I was in school, I decided that I would like to write about the moon. I’m sure many students, as well as adults, have followed the news about the astronomers who took the trip to the moon. There are beliefs that there could be life on the moon, but so far, no one has found evidence of it yet. Since we can’t take a trip to the moon, let’s find out a little bit about it.
We can all see the moon in the sky, can’t we? Sometimes it looks close to us and sometimes it seems far away. Do you know how far the moon is from the earth? It is 240,000 miles away from the earth. It is the closest to us than any other astronomical body.
Although the moon looks larger than the stars, it isn’t. Even when we see the moon when it reaches its fullest size, it is not larger than the stars.
The moon is a satellite of earth. A satellite is an object in space that orbits another object in space. The moon circles around the earth. Earth has only one moon which goes around it. Some planets have many moons. Wouldn’t it be interesting if one evening we saw several moons up in the sky? If this really happened, I think it would make front page news.!!!!
Another interesting fact is that even though the moon looks very bright, especially when it is a full moon, it does not give light from itself. The moon reflects light from the sun like a giant mirror. Have you ever seen the ad where two young women are sitting in the sun and each lady complains to the other that their hair is so shiny that it makes other people have to blink? It’s the reflection from the sun that they are talking about.
During the month, the moon seems to change in size. It starts out when it looks like a sliver and gradually day by day, it gets larger until it reaches the full size — .the full moon as we call it. The moon seems to change in shape, but it does not really change.
The moon seems to change shape when different amounts of the moon are lit by the sun. As more sunlight hits the moon, more light is reflected to the earth. The amount of sunlight the moon reflects changes a little each night.
The changes that take place regarding the size of the moon is known as phases. Another fact is that because the earth and moon are so close, the force of gravity between them is strong. The moon’˜s gravity pulls the waters of the earth toward the moon..but the water never reaches the moon. These changes in the water levels are called tide.
