What Satellites are Made Of If you mean man-made satellites ... Traditionally the main structure has been made of aluminum, although many now are some sort of composite. Usually it's some sort of graphite fiber-polycyanate face sheet over aluminum honeycomb, though it varies a lot by manufacturer and application.
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.
