Or, to put it in another way, two scenarios of moons in identical orbits. Which has the obvious use case that one can obtain a lower bound for the tidal heating through a simple calculation.īut is this assumption anywhere close to the truth? As such, a rotating body will always receive more heat than a non-rotating one. ![]() By contrast, a rotating body can very much experience tidal heating even when in a completely circular orbit.Īs a naive assumption, a rotating body will still receive heating from the deformation caused by an eccentric orbit, with some additional heat added through the periodic deformation caused by the rotation. ![]() In that case, the satellite comes closer to the planet during one part of its. For instance, for a tidally locked body, the heating depends on the eccentricity, with no heating at zero eccentricity. In fact, tidal forces can heat the interior of a satellite in an elliptical orbit. These two processes aren't completely equivalent. These data overall more closely resemble what is expected for a tidal. ![]() Tidal heating of a tidally locked moon is relatively straight forward to calculate, even though details of its internal structure is hard to work out in the first place.īy contrast, tidal heating due to tides of a rotating body is much more involved. La seconda potrebbe essere il riscaldamento mareale.
