a moon
A Satellite (like our moon) Orbiting bodies are in fact orbiting each other, so that there are binary stars (two stars of about equal size) that are orbiting each other, or even binary planets.
If the Moon is to a satellite, then Earth is to a planet. The Moon is a natural satellite orbiting Earth, just like artificial satellites orbit Earth. Similarly, planets are natural satellites orbiting stars, like Earth orbits the Sun.
By orbiting the earth about once a month.
No, there are no known moons orbiting our Moon. The Moon is Earth's only natural satellite. While some artificial satellites have been placed in orbit around the Moon by various space agencies, there are no natural moons orbiting our Moon.
A moon, when referring to a natural rock like satellite, not a man made artificial satellite such as Telstar.
A satellite is not always a robotic module constructed on Earth and launched into orbit. A satellite, in fact, is any object which is orbiting another. The orbiting object is the satellite of whatever it orbits. By now you ought to be able to guess it, but if not, it is the moon.
