It depends on if your talking about Earth's moon (aka OUR moon) or just a moon in general. If your talking about OUR moon, then it is Earth's only natural satellite (satellite means an object that orbits something), and that means that it is the only non-manmade object orbiting Earth. So that makes the moon a natural satellite!
