Thanks, I had confused centrifugal force and tidal force, will fix that. The WH40k planet I stole the idea from had a really big moon that was also nearer then ours. Thanks for the suggestions I don't think gungans could work since they (as a group) seems to only keep to Naboo but rodians absolutely fit; the type of colonise sullustans would make is not the kind I am after right now, Twi'leks do fits for mountains and fit rather well with my idea for the planet. Zabraks are already on my list. Thanks for the suggestions *looks up felucians* do fit the jungles I have planets, to bad they seems to lack space faring capability. Maybe Thanks for the suggestions Have never heard of kerkoidens but they seems interesting and dugs could work; need to look up iktotchi and kaleesh but they could work. Ewoks have the same problem as felucians, they lack the technology needed to colonise other worlds.
