Mean motion, in the context of celestial mechanics, refers to the average angular speed at which an orbiting body travels around a primary body, typically expressed in degrees or radians per unit time. It provides a way to quantify how fast an object moves in its orbit, ignoring the gravitational influences that cause variations in speed due to the elliptical nature of most orbits.
