It does seem to be >assumed that these masses are single bodies. <snip> Note that these superjupiters are in the order of several thousand earth masses, which would imply a heck of a lot of moons. But I suppose we ought to expect moon systems like those we see in our solar system where a number of satellites carry a small fraction of the total mass/momentum, and there might well be more surprising arrangements out there. This is a point that I've often wondered about, Martin. It doesn't have to be the planet that hosts life or water but one or more of its satellites. Of course Arthur C. Clarke is well ahead of us on this point having claimed that Jupiter's Europa might be harbouring life and I believe we have Titan as well. Don Ledger Listen to 'Strange Days...
