Answers
Answer:
Artificial satellites are created by humans to serve a specific purpose. Satellites can be used for communication, television, military operations, and scientific exploration. While they can be used to send and receive simple signals, researchers can also use satellites to observe the earth's surface.
Answer:
A satellite is a body orbiting a planet such as the earth. That body can be made by humans, or it can be natural. The moon is earth's only natural satellite, but we have a lot of artificial ones. The brightest artificial satellite in the sky is the International Space Station. Artificial satellites are used by humans in myriad ways. Some are used to send and receive signals without directly observing anything on the ground. This is the case with communication satellites for example.
