Figure Parameters of Ganymede

Abstract

The second zonal and second sectorial Stokes parameters of Ganymede determined on the basis of Galileo spacecraft orbit dynamics (June and September 1996) are used to determine the triaxial level ellipsoid of Ganymede. The polar and the equatorial flattening are of the same order in magnitude, about 5 × 10−4, the secular Love and tidal numbers amount 0.80 and they clarify the equilibrium state of Ganymede. The tidal rotational and orbital dynamics and tidal evolution of the Jupiter-Ganymede system differ significantly from those of the Earth-Moon system.
