Satellites are objects that rotate around another object. Such as the moon when it rotates around the Earth. Some satellites are also man-made objects. An example of a man-made satellite is a weather satellite. Some satellites are moons that go around another planet or object in space.
Weather satellites are satellites that take pictures and send messages to the computers that news reporters use to try and guess what the weather might be. There are also satellites that let us make long distant calls. Like if you are in the U.S.A. and you called someone in Italy the only way you could of called that person is by using a satellite.
Satellites help us very much. For instance if we didn't have weather satellites we might have really bad weather. If we were not ready we might get hurt if we didn't have satellites to forecast the weather. We also have satellites for our television so that we can have more channels on our television. If our Earth was not a satellite to the Sun we might not have light on the Earth. Also all the other planets are satellites too because they all rotate around the Sun. Even other planets have moons that rotate around them, that also makes them satellites. There are so many satellites in the solar system. Scientists are still working on a new satellite that can go out of our galaxy so it can take pictures of the solar system.
There are more man-made machines in the solar system today. Like the spacecraft that took the first man to the moon. There are satellites like all the satellites in the solar system. There are lost man-made satellites. Some of them could have exploded.
Some satellites get sucked into orbit. Some take pictures and then get lost and can never send back pictures. Some even get taken apart by all of the pressure that squeezes it together and makes it break into millions of pieces. Or it just shuts down. So there are many different satellites and they help the scientists help us learn more about our Earth and all the different planets.
