Definitions for "Mean anomaly"
Keywords:  anomaly, perigee, orbit, angular, zcy
in undisturbed elliptic motion, the product of the mean motion of an orbiting body and the interval of time since the body passed pericentre. Thus the mean anomaly is the angle from pericentre of a hypothetical body moving with a constant angular speed that is equal to the mean motion. (See true anomaly; eccentric anomaly.)
The anomaly which would exist if a planet orbited at a uniform speed in a circular orbit.
Represents the angular distance from the perigee point to the satellites mean position. Measured in degrees along the orbital plane in the direction of motion.
