Laythe has no real-world analogue. In the real-world [[w:Jupiter|Jupiter system]], the moons [[w:Ganymede (moon)|Ganymede]], [[w:Europa (moon)|Europa]] and [[w:Io (moon)|Io]] form a group with an [[w:Orbital Resonance|orbital resonance]] just like KSPs [[Tylo]], [[Vall]] and Laythe. But while Tylo and Vall have a certain resemblance to their real-life counterparts, Laythe is very unlike the volcanic, atmosphere-less, dry Io. Though Laythe has liquid water on its surface, the temperature there is below 0 degrees Celsius. This means that Laythe's oceans must contain another compound, most likely ionic, such as salt.

According to developer NovaSilisko, Laythe is planned to have volcanic, probably cryovolcanic, activity and high radiation levels in later versions, making it a much more hostile moon than now ({{Check version|0.23}}).<ref>[http://forum.kerbalspaceprogram.com/showthread.php/28451-Could-Laythe-actually-exist-with-real-physics?p=349683&viewfull=1#post349683 Forumpost from NovaSilisko]</ref><ref>[http://forum.kerbalspaceprogram.com/threads/29807-Planet-Ideas-And-Names-For-The-Future-Of-Kerbal-Space-Program?p=447959&viewfull=1#post447959 Post from NovaSilisko]</ref>

Although Laythe has liquid water on its surface, its polar regions have temperatures below zero degrees Celsius even outside its ice caps. This means Laythe's [[ocean]]s must contain another compound which reduces its freezing point, most likely ionic, such as salt. Surface samples indicate that much salt is present on Laythe's surface. According to EVA reports, the air can be breathed by [[Kerbal]]s. The air, however, does have a strange smell about it. It is therefore possible that there are also high concentrations of salt in the air, as well as on the surface, assuming that the salt is sodium chloride. The smell could also be sulfur, as Laythe is hinted to have high amounts of volcanic activity.

Laythe has an [[atmosphere]] thick enough and warm enough to support liquid water on its surface.  The atmosphere has a mass of approximately 2.4×10<sup>16</sup> kilograms, a sea level pressure of 60.795 kilopascals (0.6 atmospheres), and a depth of 50,000 meters.  Compared to the atmosphere of [[Kerbin]], Laythe's atmosphere has 1/2 the mass and 3/5<sup>ths</sup> the surface pressure. The sea level pressure on Laythe is equivalent to that at an altitude of 3,287 m on Kerbin. The atmosphere contains oxygen ,can support combustion and is breathable by Kerbals. Laythe is the only moon in the game that has an atmosphere.

 +
The average [[w:Molecular_mass|molecular weight]] of Laythe air is 28.9644 g/mol, and its [[w:Heat_capacity_ratio|adiabatic index]] is 1.40.  These values suggest a compostion very similar to Kerbin, and to [[w:Atmosphere_of_Earth|Earth]] — likely nitrogen and oxygen.

Like all other atmospheres in the game, Laythe's atmosphere fades exponentially as altitude increases.  The [[w:Scale_height|scale height]] varies with altitude.  The pressure-altitude profile is globally constant and independent of temperature.  The following table gives the atmospheric pressure at various altitudes above sea level.

The variation of temperature with height suggests the presence of an earthlike [[w:Troposphere|troposphere]], [[w:Stratosphere|stratosphere]] and [[w:Mesosphere|mesosphere]]. The warm surface temperatures rapidly decrease as the alitude increases to 5 km. The stratospheric region, where temperature rises as altitude increases, spans the region between the altitudes of 10 km and 22 km.

With proper [[aerobraking]] near Laythe and Jool, reaching Laythe may require the least delta-V of all of Jool's moons. When approaching Jool on a Hohmann transfer orbit from Kerbin, aerobraking with a Jool periapsis of 119.5 km will put your apoapsis roughly near Laythe's orbit.
+
Air temperatures vary with latitude and time of day.  At the equator, sea level temperatures vary between a nighttime low of 9 °C and a daytime high of 15 °C. Mid-latitudes are only slightly cooler than the equatorial zone — at latitudes below 63°, the sea level temperature never drops below 0 °C.  At the poles, the temperature varies between -26 °C and -24 °C.  The globally averaged sea level temperature is approximately 9 °C. Since Laythe has no axial tilt, there are no seasonal temperature variations.
  
−
Another way is to approach Laythe directly, with proper timing and orbit adjustments done on the way to Jool. Laythe's orbital period makes it easy target to time and allows less Δv on arrival (only 2000 m/s), thus aerobraking on Laythe is lighter than on Jool. Diving to ~22 km will almost circularize the (retrograde) orbit.
+
Laythe's surface temperatures are warmer than would be expected based on its distance from the sun. This suggests the possibility that Laythe generates its own heat, likely [[w:Tidal_heating|tidal heating]]. It could also be caused by a higher rate of greenhouse gases such as carbon dioxide or nitrous oxide than on Kerbin.

===Oxygen===

As previously mentioned, Laythe's atmosphere contains [[w:Oxygen|oxygen]], enabling [[jet engines]] to function. Even though there is a lower concentration of oxygen than on Kerbin, plus an unknown trace gas, most likely ozone, this oxygen almost surely has to be generated somewhere on Laythe. Molecular oxygen is extremely unstable compared to other atmospheric gases, and is even capable of reacting with itself to form ozone under certain conditions. Because of this unstable molecular oxygen must constantly be replaced for it to remain in any meaningful quantity in an atmosphere. This fact, combined with Laythe's extremely high concentration of liquid water, indicates that there may be unicellular life on the moon. While it is possible that this is the case, it is also possible that the moon has a self-sustaining chemical process that constantly replenishes its oxygen reserves, such as double ionization of sulfur dioxide.<sup>[https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9390983/ [source]]</sup>

Laythe is the innermost of the five natural satellites of Jool. Although mostly covered in seas, Laythe has numerous rocky, sandy islands. Laythe is tidally locked to Jool. Synchronous orbits around Laythe are not possible, as they would lie outside of its SOI, at a radius of 5,186,399 meters. A circular archipelago prominent in surface maps of the moon suggests that Laythe suffered a massive impact in its distant past.

Achieving a stable orbit around Laythe from sea level requires a delta-V of ≈2900 m/s.

Laythe has no real-world analogue. In the real-world Jupiter system, the moons Ganymede, Europa and Io form a group with an orbital resonance just like KSP's Tylo, Vall and Laythe. But while Tylo and Vall have a certain resemblance to their real-life counterparts, Laythe is very unlike Io, which is dry, volcanic, and only has a tenuous atmosphere. Instead, Laythe's liquid ocean and dense atmosphere invite comparison with the Saturnian moon Titan, but Laythe is 3 times warmer in absolute temperature.

Although Laythe has liquid water on its surface, its polar regions have temperatures below zero degrees Celsius even outside its ice caps. This means Laythe's oceans must contain another compound which reduces its freezing point, most likely ionic, such as salt. Surface samples indicate that much salt is present on Laythe's surface. According to EVA reports, the air can be breathed by Kerbals. The air, however, does have a strange smell about it. It is therefore possible that there are also high concentrations of salt in the air, as well as on the surface, assuming that the salt is sodium chloride. The smell could also be sulfur, as Laythe is hinted to have high amounts of volcanic activity.

“ When Laythe was first discovered, it was not entered in the records because the scientist in charge thought he was looking at Kerbin.


Luckily this error was corrected when a plucky intern informed him that “telescopes don’t work that way.”

The intern was shortly afterwards “promoted” and moved to the experimental rocket testing program.''

“ Do you like gleaming oceans, sandy beaches, and breathable air? Pack your bags and take a trip to the Jewel of Jool, Laythe! The Kerbin-like atmospheric density is sure to keep you comfortable, whether you're picnicking on the shore or studying impact craters.

Laythe has 10 biomes. Laythe consists primarily of a huge ocean, called The Sagen Sea, with another ocean called the DeGrasse Sea and some small Peaks, Dunes and Shores biomes. It also has a Poles biome.

Atmosphere

Temperature and pressure of Laythe's atmosphere as a function of altitude.

Laythe has an atmosphere thick enough and warm enough to support liquid water on its surface. The atmosphere has a mass of approximately 2.4×1016 kilograms, a sea level pressure of 60.795 kilopascals (0.6 atmospheres), and a depth of 50,000 meters. Compared to the atmosphere of Kerbin, Laythe's atmosphere has 1/2 the mass and 3/5ths the surface pressure. The sea level pressure on Laythe is equivalent to that at an altitude of 3,287 m on Kerbin. The atmosphere contains oxygen ,can support combustion and is breathable by Kerbals. Laythe is the only moon in the game that has an atmosphere.

The average molecular weight of Laythe air is 28.9644 g/mol, and its adiabatic index is 1.40. These values suggest a compostion very similar to Kerbin, and to Earth — likely nitrogen and oxygen.

Like all other atmospheres in the game, Laythe's atmosphere fades exponentially as altitude increases. The scale height varies with altitude. The pressure-altitude profile is globally constant and independent of temperature. The following table gives the atmospheric pressure at various altitudes above sea level.

Altitude (m) Pressure (Pa) Pressure (atm)
0 60 795 0.600
2 500 47 153 0.465
5 000 34 495 0.340
7 500 24 914 0.246
10 000 17 786 0.176
15 000 9 351 0.092
20 000 4 782 0.047
25 000 2 671 0.026
30 000 1 507 0.015
40 000 363.5 0.004
50 000 0 0.000

The variation of temperature with height suggests the presence of an earthlike troposphere, stratosphere and mesosphere. The warm surface temperatures rapidly decrease as the alitude increases to 5 km. The stratospheric region, where temperature rises as altitude increases, spans the region between the altitudes of 10 km and 22 km.

Air temperatures vary with latitude and time of day. At the equator, sea level temperatures vary between a nighttime low of 9 °C and a daytime high of 15 °C. Mid-latitudes are only slightly cooler than the equatorial zone — at latitudes below 63°, the sea level temperature never drops below 0 °C. At the poles, the temperature varies between -26 °C and -24 °C. The globally averaged sea level temperature is approximately 9 °C. Since Laythe has no axial tilt, there are no seasonal temperature variations.

Laythe's surface temperatures are warmer than would be expected based on its distance from the sun. This suggests the possibility that Laythe generates its own heat, likely tidal heating. It could also be caused by a higher rate of greenhouse gases such as carbon dioxide or nitrous oxide than on Kerbin.

Atmospheric flight

The thickness of Laythe's atmosphere makes it suitable for aerobraking and the use of parachutes.

With proper aerobraking near Laythe and Jool, reaching Laythe may require the least Δv of all of Jool's moons. Another way is to approach Laythe directly, utilizing proper timing and making orbital adjustments on the way to Jool. Laythe's orbital period makes it an easy target to time and will have required less Δv on arrival (only 2000 m/s). As such, aerobraking on Laythe is less extreme than on Jool.

Landing on higher points of Laythe's surface has to be done with the help of retro-burns, as parachutes alone will not suffice to sufficiently lower a craft's velocity for landing.

Jet engines work in Laythe's atmosphere due to the presence of oxygen. However, the air-intake efficiency is lower there.

Even though there is a lower concentration of oxygen than on Kerbin, plus an unknown trace gas, most likely ozone, this oxygen almost surely has to be generated somewhere on Laythe.

While it is possible that this is the case, it is also possible that the moon has a self-sustaining chemical process that constantly replenishes its oxygen reserves, such as double ionization of sulfur dioxide.[source]

Laythe is the most science-rich body in the Joolian moon system. Even though Tylo has a slightly higher science multiplier for both surface and orbit, Laythe's atmosphere and oceans allow a lot more experiments to be performed, which means the total science output is higher.

Trivia

  • Laythe's DeGrasse Sea and Sagen Sea are likely named after Neil DeGrasse Tyson and Carl Sagan, two famous physicists.
  • Laythe seems very similar to what happened to Europa in 2010: Odyssey Two.
  • Laythe may also be a reference to the planet Damogran from the radio/tv/book/movie series The Hitchhiker's Guide to the Galaxy, as they are almost, but not quite, entirely not unlike one another.
  • According to former developer NovaSilisko, Laythe was planned to have volcanic activity and high radiation levels in later versions, making it a much more hostile moon[1][2].
