Really? Which satellites (moons) in our solar system are not
tidally locked to their planets?

Hyperion + Saturn

Correct. Hyperion is locked in a 3:4 orbital resonance with Titan.


Wow... see what happens when you keep your eyes open... you learn things!


The day I stop learning things I'll be dead (which recalls the
uncomfortable CM Kornbluth line).
Does anyone even know if the outer moons of Jupiter and Uranus are
tidally locked? The Jovian moons are in retrograde orbits and are
supposed to be captured asteroids like Phobe, which isn't locked, for
instance.
Neptune's moon Nereid isn't locked, either.


Okay, now I'm confused. After much Googling, I was under the impression
that Hyperion was the only satellite (moon) in our solar system that is not
tidally locked.
