Orientation of the tidal bulge. Panel (a) displays the bulge of the ice shell under the action of the static tide, and the other panels display the bulge under the action of the total tide, depending on whether the shell is hard (panel (b)) or soft (panel (c)). For given values of γS and γice (angles of Saturn in its epicycle and of the shell, respectively), the resulting orientation of the bulge (γbul) depends on the shell’s hardness. When it is hard, the shell hardly changes its shape relative to γice. When it is soft, the bulge nearly points at Saturn, whatever the value of γice. The hardness parameter is defined in Equation (27). -- The Planetary Science Journal

Enceladus’ Tidal Heating: A Simple Approach

by Keith CowingOctober 11, 2025October 11, 2025

Saturn’s moon Enceladus has a global ocean that is covered by an ice shell. The moon’s eccentric orbit forces the shell to librate, which distorts the shell and thereby generates […]
