A satellite is an artificial object that is deliberately sent into orbit in space, usually in order to send, receive or bounce back information to different areas of Earth. Artificial satellites are man-made satellites, they differ to natural satellites such as the Moon which orbits Earth and Earth itself which orbits the Sun.
Satellites, of course! Satellites are any objects that revolve around (orbit) another object in space. Some satellites are natural, while others are artificial (man-made). The moon is an example of a natural satellite that orbits the Earth. We're going to focus, though, on the man-made satellites. Artificial satellites are machines that humans launch into orbit, usually around the Earth. Artificial satellites can be sent to orbit other planets, too. For example, there are currently satellites orbiting the Moon, the Sun, and several other planets, including Mercury, Venus, Mars, and Saturn.
