Oh, good call, I didn’t think of that! Assuming I did my sums right, the Roche limit probably destroys the fourth innermost moon, but it still leaves the big four (which are the fifth through to ninth in ascending order of size of orbit). They’re quite substantially farther out than the prior four

There are also like eighty smaller moons even farther out, but they don’t meet the roundness criterion to be a planet because they are too small
