Abstract
We determine constraints on the ice shell and ocean of Enceladus from the observed libration at orbital period by assessing the effects of uncertainties in the size, density, rigidity, and viscosity of the internal layers and of the non-hydrostatic structure on the libration. The observed libration amplitude implies that the average thickness of the ice shell is between 14Â km and 26Â km and that the ocean is 21Â km to 67Â km thick.
