Maybe a duplicate of the one you suggested? But that answer only gives a vague idea of when that happens.

When will Callisto be in orbital resonance with the rest of Jupiter's big moons?

The [four Gallilean moons of Jupiter](https://en.wikipedia.org/wiki/Moons_of_Jupiter) (from innermost) are Io, Europa, Ganymede, and Callisto. Io, Europa, and Ganymede are in a 1:2:4 [orbital resonance](https://en.wikipedia.org/wiki/Orbital_resonance). Callisto's orbital period is 16.689 days, which is not much more than twice Ganymede's period of 7.1546 days.

According to the current estimation of the tidal dissipation in the Jovian system, we expect that Callisto will be captured into resonance in about 1.5 billions of years, forming 1:2:4:8 resonant chain with the other Galilean moons.
