Reply to comment by gryfter_13 in TIL the largest moon in our solar system, Ganymede, is larger than the planet of Mercury by Jugales

I believe that's mostly Io. Isn't Ganymede the farthest of the big 4 from jupiter?

Callisto is the outer moon. Tidal effects on Ganymede are smaller than the other two of the Laplace resonance, it's both the outer (and so slower) and the least eccentric (0.0011).

Callisto isn't part of that resonance.
