Planetary gears refer to gear systems that, in addition to being able to rotate around their own axis of rotation like fixed-axis gears, also rotate with the planet carrier around the axes of other gears. Rotation about its own axis is called "rotation", and rotation about other gear axes is called "revolution", just like the planets in the solar system.
