Tylo is the largest moon of Jool and the Kerbol System, and the largest celestial body without an atmosphere. It is the analog for Ganymede. It is the third moon from Jool, is the same diameter as Kerbin, and is tidally locked. Tylo orbits Jool in roughly nine days. Synchronous orbits around Tylo are impossible, as they would lie far outside of its SOI at a radius of 14,758,067 meters.
Tylo is a relatively difficult target to visit. Its gravity is similar to Kerbin's, but without an atmosphere, there is no way to aerobrake, and a large amount of fuel must be used to land and take off. However, due to its large gravity well, Tylo is ideal for a gravity assist to enter or leave the Jool system with minimal fuel consumption.
|“|| Tylo was the first moon of Jool to be discovered by the Kerbal Astronomical Society. After many failed attempts to take a flawless picture of Jool to hang on the office walls, it was finally discovered that the wandering white smear was indeed a moon.
Scientists speculate that the view from the surface with Laythe, Vall, and Jool overhead must be quite something.
Tylo has a rocky surface. It has a varying elevation between 0 meters (Tylo baseline height) and peaks of more than 11290 meters. Tylo's surface looks similar to that of Mün, but has much fewer impact craters (especially on the side facing away from Jool) and is more uneven.
Due to the coloring of the surface of Tylo, it is likely that it is covered in a rhyolite layer of rock, nickel, a little cobalt, and some sort of ice and dust spread by meteorite impacts but as there is no official way to determine the composition of the moon this is only hypothetical. This explains why Tylo has a rather bright and white surface.
Because it is very large in comparison to other moons, it is unlikely that it is a captured planet. For a planet of this size, Jool would have to be much larger and denser to produce a large and strong enough gravitational well. It is unknown why Tylo hasn't formed an atmosphere.
Because of its high gravity and lack of an atmosphere, Tylo is very hard to land on and reach orbit from. However, low altitude orbits at high speeds can be achieved for these same reasons.
Tylo has 8 biomes. Three "Major Craters" are shown in different colors in debug view, but appear to be the same biome. It is unknown, if this is a bug or was simply overlooked by Squad.
Tylo has the second-highest science multipliers in the game. The only orbit with a higher multiplier is the sun and the only surface with a better multiplier is that of Eve. Unfortunately Tylo has no atmosphere, which means that there is one less zone to conduct experiments in and that some experiments do not work at all. That means that it is only the second most science-rich Joolean moon after Laythe.

- Kerbin has the same equatorial radius as Tylo (600,000m) yet Tylo's surface gravity is much lower than Kerbin. This is most likely because Tylo is composed of low density matter.
- There are two known Easter eggs on Tylo.
