Io is locked in an orbital relationship with Europa and Ganymede known as the Laplace resonance. What is the specific ratio of their orbits?

Answer

1:2:4.

The Laplace resonance is defined by a precise 1:2:4 ratio, meaning that for every one orbit Io completes, Europa completes two, and Ganymede completes four.
