'''Tylo''' is not just the largest of the five [[moon]]s of [[Jool]], but the largest moon overall in the KSP solar system. It has a rocky surface. It is extremely challenging to land on because it possesses a similar gravity well to [[Kerbin]] itself, while lacking the benefit of an atmosphere to brake in. But due to its large gravity well, it is ideal for performing a [[Tutorial: Gravity Assist|gravity assist]] to enter or leave the Jool system safely and with minimal fuel consumption.

'''Tylo''' is the largest moon of [[Jool]] and the [[Kerbol System]], and the largest celestial body without an [[atmosphere]]. It is the analog for [[w:Ganymede (moon)|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.
  
Having a spacecraft orbiting very close to the surface can give you orbit periods of about 29 minutes going about 2,170 m/s. Like the other large Joolian moons, Tylo is tidally locked. Synchronus orbits around Tylo are not possible, as they would lie 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.

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.

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.

According to former developer NovaSilisko, Tylo was planned to be made into a high-contrasting body like Saturn's moon Iapetus.[1]

In-game Description

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”.''

Kerbal Astronomical Society

Topography

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.

Biomes

Tylo has 9 Biomes. It mostly consists of generic Low-, Mid- and Highlands with some Mara and Minor Craters scattered in between. There are four distinct Craters. Previously three of these Craters were simply named Major Crater, the reason for this oddity not being known.

Science

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 Joolian moon after Laythe.

Trivia

  • 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 lower density matter.
  • Tylo is one of the few bodies in the solar system with almost totally manually-created colors (i.e., it uses a color map instead of procedural coloration). It only has a tenuous coat of a height-based darkening, and some simple noise. The only other manually-colored objects in the game are the Mun and Jool.
  • The Gagarin crater on Tylo was most likely named after Yuri Gagarin, the first man in space.
  • The Grissom crater on Tylo was most likely named after Virgil "Gus" Grissom, the second American in space.
  • The Galileo crater on Tylo was most likely named after Galileo Galilei who is widely considered to be the inventor of the telescope.
  • The Tycho crater on Tylo was most likely named after Tycho Brahe who helped overturn a belief in favor of the heliocentric theory.
  • There are two known Easter eggs on Tylo.
Spoiler:
One is Carl Sagan's face (which is now broken) on a mountain and the other is a cave-like underground formation. The cave-like formation used to be below the surface, but as of 1.3 it is back at the surface.
