java.lang.Object org.orekit.bodies.AbstractCelestialBody org.orekit.bodies.MeeusMoon
public class MeeusMoon
This class implements the Moon ephemerides according to the algorithm of Meeus. It only provides the position. Note that it is not possible to build this Moon from the CelestialBodyFactory.
See "Astronomical Algorithms", chapter 45 "Position of the Moon", Jean Meeus, 1991.Note that pole information allowing to define inertially-centered frame and rotating frame are defined in
IAUPoleFactory
since Meeus model does not provide the information.
