the Kyptron island is used, always seemed dumb, but this is a nice use for it, however I do wonder (I know this has already been said) what effect this might have on Supermans powers.
That said its possible for it to have gotten far enough away from Earth, not to effect Superman,
I thought the point of the Krypton island was that it was made of (or at least contained significant amounts of) Kryptonite.
Kryptonite weakens and kills Superman regardless of how far he is or isn't from earth.
I make no claims to being a massive superman fan, but isnt Kryptonite at harmful at a certain distance to Superman? once Superman is a certain distance away from it, he is fine.
Same goes for the Krypton island, so as long as the moon is far enough way Superman should be ok.
