satellite
A body that revolves around a larger body, normally either a planet or an asteroid; also known as a moon. For example, Europa is a satellite of Jupiter, and Dactyl is a satellite of the asteroid Ida. Since 1957 the term has also been applied to human-made objects, so that a distinction is now drawn between natural and artificial satellites. Several moons are larger than Pluto and two (Ganymede and Titan) are larger than Mercury.
