Woah woah woah... Tylo has a surface gravity amount of 7.85?! Is that right? I mean I kinda expected Laythe to, and I suppose Tylo isn't a whole lot smaller, but it seems weird for them to be exactly the same, as well as the float point gravity of Jool... I kinda expected Tylo to have gravity more along the lines of Duna, maybe a bit more. Honestly, if it's that high... why wouldn't it have some atmosphere? I mean I know that a poor magnetosphere has some to do with it as well (especially when closer to the sun and the solar winds are higher), but it isn't close to the sun, and has more than twice the surface gravity of Mars (and Duna), and Mars is closer as well as has an awful magnetosphere. Something doesn't seem right to me about Tylo having that high a surface gravity...
