  • n. An orbital parameter of a celestial body (in an elliptic orbit); the mean motion multiplied by the time since the last passage through periapsis; the angle PCM (measured in radians) defined by P = the periapsis, C = the center of the elliptical orbit, and M = the mean planet.

  • I know! I really prefer the eccentric anomaly.

  • Why can't the anomaly just be nice like everybody else?

  • "In celestial mechanics, the mean anomaly is a parameter relating position and time for a body moving in a Kepler orbit. It is based on the fact that equal areas are swept at the focus in equal intervals of time."

    "The mean anomaly is one of three angular parameters ('anomalies') that define a position along an orbit; the other two being the eccentric anomaly and the true anomaly."
