One conclusion is that, "other things being equal" (such as formula_12 and formula_23), a large moon will lock faster than a smaller moon at the same orbital distance from the planet because formula_6 grows as the cube of the satellite radius formula_29. A possible example of this is in the Saturn system, where Hyperion is not tidally locked, whereas the larger Iapetus, which orbits at a greater distance, is. However, this is not clear cut because Hyperion also experiences strong driving from the nearby Titan, which forces its rotation to be chaotic.
