Jool is a gas giant and the fifth planet of the Kerbolar star system.
Atmosphere
Although Jool has a radius ten times greater than Kerbin, its atmosphere begins approximately twice as high (138.2 km). It is also extremely dense, well suited for aerobraking from a high-speed inter-planetary intercept.
Closer to the surface, the physics of the game start to break down. Due to its extremely thick atmosphere, terminal velocity is so low that lighter spacecraft will not even need parachutes or retrorockets. It is not impossible to land on it's solid surface, though spacecraft are inevitably and invariably devoured by the Kraken. If a kerbonaut is put on EVA he will not be destroyed, making long term landings feasible.
Natural Satellites
Jool has four natural satellites:
The ocean moon Laythe, about to eclipse Jool.
- The ocean moon Laythe, which has an atmosphere and is both the largest and closest to Jool. Due to it's high orbital velocity, it is somewhat challenging to reach.
- The ice moon Vall, which is the second largest and second closest. It's orbital path and velocity sit almost exactly between Layth and Tylo.
- The rocky moon Tylo, similar to Kerbin's Mun, is the third body orbiting Jool. It is perhaps the easiest of the four to reach, with a stable orbit, large gravity well, and (relatively) slow orbital velocity.
- The captured asteroid Bop, the smallest body orbiting Jool. Due to it's distant, erratic orbit and low gravity, it is also challenging to reach.
Laythe, Vall, and Tylo are in a Laplace resonance, with orbital periods of 1:2:4 respectively.
