Jool is a gas giant and the fifth planet of the Kerbolar star system. It is the most distant of the five planets, and hardest to reach. It is one of the most appealing targets for missions, however, because of its large and complex system of four moons: Laythe, Vall, Tylo and Bop.
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 its 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:
Laythe, Vall, and Tylo are in a Laplace resonance, with orbital periods of 1:2:4 respectively. |
 The ocean moon Laythe, about to eclipse Jool. |
