Paging astronomers

[ffutures]

For a plot point in a possible future Supergirl story I've been wondering about Krypton's moons. This page puts together information in the Superman comics etc. and makes some guesses about the moons as described there:

My feeling on this is that they're too close to the planet and to each other, and would either drift into tidal lock or end up catapulting each other out of orbit pretty quickly. I know that there are at least a couple of astronomers on my friends list, anyone able to crunch the numbers?

That feels a lot more reasonable - many thanks for going to so much trouble.

I really hate to say how minor the plot point will be, if it happens at all; just Kara missing something because she's not very familiar with tidal cycles - especially since she's from an essentially artificial environment.

This is the first time anybody's even commented on the moons - and the figures certainly aren't carved in stone so if somebody wants to let me know how to make it work even better, I don't mind at all.
