are many things about Earth that most people do not know. It is
actually a very interesting planet. A lot of people think that
the Earth is round, but it is really pear-shaped. The top is pushed
in and the bottom bulges out! The circumference, or distance around
the Earth at the equator (or the fattest part of the "pear"),
is 24,901.55 miles.
The Earth is always moving. It spins or rotates while traveling in a big circle around the Sun. Its orbit or path around the Sun is 583,400,000 miles long. Earth travels along this path at 66,000 mile-per-hour. The Earth rotates at 1,000 miles-per-hour. That is pretty fast!
Here are some other strange facts about Earth. There is a lot of water in the Earth's atmosphere. In fact, there is enough water to cover the entire surface of the Earth with one inch of water! The atmosphere that holds all that water rises 250 miles above the Earth's surface. Our planet is located in the perfect place for our need for water. If it was any closer or farther away from the Sun, all that water would either boil away or freeze.
Earth's moon is also unique. It is one of the biggest in our solar system. When you look at the moon, you always see the same side. Many people think that Earth has a second moon. This is really Asteroid 3753, but strangely enough, it orbits the Earth.
As you can see, there is a lot more to the Earth than you thought!
