Hamowanie aerodynamiczne w atmosferze Joolu.

Mimo, że Jool ma promień 10 razy większy niż Kerbin, jego atmosfera zaczyna się 2 razy wyżej (138.2 km). Jest również bardzo gęsta, dobrze nadaje się do hamowania aerodynamicznego. O Orbitowanie zaraz ponad atmosferą daje okres orbitalny równy 94.7437 minutom, i prędkość 6,785 m/s. Zazwyczaj nie trzeba schodzić poniżej 60 km, aby rozpocząć hamowanie aerodynamiczne.

Ogólnie, ciśnienie atmosferyczne w Joolu dla wysokości wyrażonej w metrach:

${\displaystyle p_{j}=15\ e^{-altitude/9000}}$

The effects of landing on Jool's "surface" as a Kerbonaut

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 one-way sacrificial landings possible. However, as seen near the end of this video, the Kerbonaut will start to glitch out and shake uncontrollably. This only happens if you're on time warp 4. The game will later glitch and cut to a black screen with the altimeter going through numbers rapidly. Unless you restart the game, Kerbin's atmosphere will be missing.

The ocean moon Laythe, about to transit Jool.

Jool has five natural satellites:

• The ocean moon Laythe, currently the only moon possessing an atmosphere, is the closest to Jool and second largest of its moons. Due to its high orbital velocity, it is somewhat challenging to reach. Next to Eve, its size and composition make it the most similar celestial body to Kerbin
• The ice moon Vall, which is the third largest and second closest. Its orbital path and velocity sit almost exactly between Layth and Tylo.
• The rocky moon Tylo, similar to Kerbin's Mun, although it has similar gravity to Kerbin. While having the largest SOI, making it easiest to encounter, achieving orbit and landing are exceptionally difficult due to it's large gravity well coupled with lack of atmosphere.
• The captured asteroid Bop, the smallest body orbiting Jool. Due to its distant, erratic orbit and low gravity, it is also challenging to reach.

• In 0.18, a new moon was added, Pol, named so after a Pollen grain which it resembles. A yellowish/greenish moon, rocky and uneven with tall spiky mountains. It orbits Jool beyond Bop and is around twice as large. An image can be found here.

Laythe, Vall, and Tylo are in a Laplace resonance, with orbital periods of 1:2:4 respectively. Despite the fact that the moons can easily eclipse both each other and Jool, they do not.

Trivia

• Jool has roughly the same equatorial radius as the planets Earth and Venus.
