planetocentric coordinate

planetocentric coordinatehas definition Coordinates for general use, where the z-axis is the mean axis of rotation; the x-axis is the intersection of the planetary equator (normal to the z-axis through the center of mass) and an arbitrary prime meridian; and the y-axis completes a right-hand coordinate system. Longitude (see longitude, celestial) of a point is measured positive to the prime meridian as defined by rotational elements. Latitude (see latitude, celestial) of a point is the angle between the planetary equator and a line to the center of mass. The radius is measured from the center of mass to the surface point.has source: Seidelman, P. 1992 Explanatory Supplement to the Astronomical Almanac, University Science Books, Mill Valley, CA, 2001-09-27 09:32:41.0
