Atmosphere
Based upon the fact that Jool has a tenfold radius in comparison to kerbin, it can be assumed the atmosphere is also tenfold, possibly beginning at roughly 691 KM.
Natural Satellites
Jool has four natural satellites: the ocean moon Laythe, the ice moon Vall, the rocky moon Tylo and Bop. Laythe, Vall, and Tylo are in a Laplace resonance, with orbital periods of 1:2:4 respectively.
