Atmosphere
Although Jool has a radius 10x bigger than Kerbin, its atmosphere only begins roughly twice as high (140 km). It is also extremely dense, well suited for aerobraking from a high-speed inter-planetary intercept.
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.
