Discover the gas giant Jool and its fascinating moons in Kerbal Space Program. Learn about their unique characteristics and challenges for your space missions.

The Kerbal Space Program Wiki is a comprehensive, unofficial guide to Squad's space flight simulator. This section focuses on Jool, the gas giant, and its system of moons, providing essential information for players undertaking missions to this challenging region of space.

Walkthrough
  1. 1
    Jool: Jool is the fifth and largest planet in the Kerbol system, a gas giant with a complex system of moons. Its immense gravity well and atmospheric effects make it a significant celestial body to navigate.
  2. 2
    Laythe: The innermost moon of Jool, Laythe is unique for having a thick atmosphere and surface oceans, making it the most Earth-like celestial body in the game. It's a prime target for exploration and potential colonization.
  3. 3
    Vall: A large, icy moon of Jool, Vall is characterized by its dim light and frozen surface. It offers a challenging but rewarding destination for resource gathering and scientific missions.
  4. 4
    Tylo: The largest moon of Jool, Tylo is a massive, airless world with a gravity similar to Kerbin. Its size and lack of atmosphere make it a popular destination for landing practice and resource extraction.
  5. 5
    Bop: A small, irregularly shaped moon of Jool, Bop is an asteroid captured by Jool's gravity. It's known for its low gravity and unique terrain, offering a different kind of exploration challenge.
  6. 6
    Pol: The outermost moon of Jool, Pol is a small, icy body with a slightly eccentric orbit. It presents a more distant and less explored target within the Jool system.
Tips
  • Due to Jool's immense gravity, performing aerobraking maneuvers in its upper atmosphere can save significant fuel, but requires careful attention to heat and atmospheric density.
  • Each moon presents unique challenges for landing and ascent due to varying gravity, atmospheric conditions, and surface features. Plan your missions accordingly.
  • Consider using Jool's moons for gravity assists to alter your trajectory and reach other parts of the Kerbol system more efficiently.
  • Establishing a base or refueling station around Jool or its moons can be crucial for long-duration missions and further exploration.
