What is the Maximum Number of Moons that Earth Could Have? - by ET_Exists
“The surprise was that the lower mass prototypes were more limited, which we ascribe to their increased scattering probability ,” said Quarles. “The perturbations from neighboring moons are enough to cause substantial scattering within a few thousand years. We had to reduce the number of moons to account for this.”
“Tidal heating of the moons themselves may be possible, but it is unclear to the extent of the heating without performing detailed simulations,” said Dr. Quarles. “It is tempting to suggest that the innermost moon could resemble Io, but its tidal heating is in part due to mean motion resonances with the other Galilean moons. In our systems, mean motion resonances largely destabilize the satellite system because the Sun adds to each moon’s eccentricity growth and eventual scatter.
