<br />
'''Tylo''' is the third [[moon]] of [[Jool]]. It is the largest of Jool's five moons, the largest moon in the entire [[Kerbol System]], and the largest celestial body without an atmosphere. It is Kerbal Space Program's analog for [[w:Ganymede_(moon)|Ganymede]], a moon of [[w:Jupiter|Jupiter]].<br />
<br />
Landing on Tylo is extremely challenging. Its gravity is similar to [[Kerbin]]'s, but aerobraking is impossible, since there is no [[atmosphere]]. However, due to its large gravity well, Tylo is an ideal target for a [[Tutorial: Gravity Assist|gravity assist]] to enter or leave the Jool system safely and with minimal fuel consumption.<br />
<br />
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. Synchronous orbits around Tylo are not possible, as they would lie outside of its SOI, at a radius of 14,758,067 meters.<br />
<br />
== Topography ==<br />
Tylo has a rocky surface. It has a varying elevation between 0 meters (Tylo baseline height) and peaks of more than 11290 meters. <br />
<br />
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.<br />
<br />
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, some sort of ice and dust, spread by meteorite impacts.<br />
Although 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 a mystery why Tylo hasn't formed an atmosphere.<br />
<br />
Because of it's 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.<br />

<div>{{:Bop/Data}}<br />
'''Bop''' is one of the five [[w:Natural satellite|natural satellites]] of [[Jool]]. It seems to be a [[captured asteroid]] and has certain similarities to [[Gilly]], another pressumed captured asteroid orbiting Eve. Bop has a large crater with a white rim. Some of its mountains rise nearly 22 km above the surface. The brownish color may come from solid carbon or iron oxide.<br />
<br />
== Easter Eggs ==<br />
A dead Space Kraken is located on Bop.<br />
<br />
== Topography ==<br />
Bop is mostly mountainous with few flat surface areas.<br />
<br />
A noticeable feature on Bop is a very large impact crater on one side of it.<br />

<div>{{:Eeloo/Data}}<br />
<br />
'''Eeloo''' is a [[w:dwarf planet|dwarf planet]] that was released in {{version|0.18.2}} as a Christmas gift to the KSP community. It is the seventh and farthest planet from [[Kerbol]] most of the time, though its orbit intersects [[Jool]]'s, passing in front of it for a minority of its revolution period. The two planets are locked in a 3:2 resonance, which, coupled with their different inclinations, ensures they cannot collide.<br />
<br />
Eeloo has just 3.5% more gravity than the [[Mun]] and is very similar in size. Like the Mun, it has no atmosphere. The physical characteristics of Eeloo are most likely an analogue of the ice moon [[w:Enceladus (moon)|Enceladus]], and its orbit is similar to that of [[w:Pluto (dwarf planet)|Pluto]], though both bodies are known to have a tenuous atmosphere. Eeloo's appearance is reminiscent of the Galilean Moon Europa.<br />
<br />
== Topography ==<br />
The surface of Eeloo is relatively smooth and covered in gray-white ice, with deep canyons exposing the brownish rock below. A few craters are visible, but not nearly as one might expect for a body without an atmosphere. Its highest points are near the equator and are almost 3.9 km high, while the lower areas can go lower than sea level. <br />
<br />
Eeloo's surface lacks ground scatter.<br />
<br />
== Orbits ==<br />
Eeloo's far and large orbit, in addition to its low gravity, make encounters challenging. Its distance from [[Kerbin]] also tends to make missions very lengthy.<br />
<br />
A synchronous orbit around Eeloo is possible, at an altitude of ~683.9 km. <br />
<br />
== Communication ==<br />
Using the Remote Tech plugin, path lengths from Kerbin can reach up to around 127 [[w:gigametre|Gm]] (127 billion meters), resulting in a round trip delay longer than 14 minutes. Even at the closest approach, the communication delay is more than 6 minutes.<br />
<br />
== Planned Features ==<br />
There are plans for Eeloo to become the moon of a second gas giant and have an active surface, with ''cryovolcanic'' phenomena.<ref>http://forum.kerbalspaceprogram.com/showthread.php/35829-Eeloo-Discussion!?p=398040&viewfull=1#post398040 (outdated link)</ref> It is unknown what Eeloo's parent planet will look like.<br />

<div>{{:Kerbin/Data}}<br />
<br />
'''Kerbin''' is the home planet of the [[Kerbal]]s, the location of the [[Kerbal Space Center|Space Center]], and the main focus of [[Kerbal Space Program]]. It is also the [[w:Earth|Earth]] analog for the game and has two [[moon]]s, named '''[[Mün]]''' and '''[[Minmus]]'''.<br />
<br />
Kerbin is the third planet in [[orbit]] around the star [[Kerbol]]. It is the third largest planet (after [[Jool]] and [[Eve]]) and the fourth largest celestial object around Kerbol (with [[Tylo]], a moon of Jool, being slightly larger).<br />
<br />
Reaching a stable orbit around Kerbin is one of the first milestones a player might achieve in the game. Doing so with a fuel-optimal ascent<ref>A fuel-optimal ascent is one which (a) minimizes velocity losses to gravity and [[atmosphere|atmospheric drag]] and (b) launches eastward (toward the 90 degree heading) to gain 174.5 m/s of orbital velocity for free, thanks to Kerbin's rotation.</ref> requires a [[delta-V]] of ≈4500 m/s,<ref>See [http://forum.kerbalspaceprogram.com/showthread.php/24017-Least-delta-v-to-orbit this challenge on the forum] and a popular [http://i.imgur.com/CEZS1.png Kerbin delta-V chart]</ref> the second largest of all celestial bodies with a solid surface after [[Eve]]. Many interplanetary missions expend over half of their delta-V in reaching Kerbin orbit. Many Earth-based interplanetary spaceflights also do so, leading one observer to remark:<br />
{{Quote|If you can get your ship into orbit, you're halfway to anywhere.|Robert Heinlein|quoted on page 194 of ''A Step Farther Out'' by Jerry Pournelle}}<br />
<br />
== Topography ==<br />
[[File:Kerbin_heightmap.jpg|thumb|left|Topographical representation of Kerbin's surface as of .18.2. Click for high resolution. by Zeroignite]]<br />
Kerbin has a roughly equal distribution of surface liquid water and solid land, with polar icecaps and scattered deserts. Some of its mountains exceed 6 km in height, with the tallest peak being 6761 m in altitude.<br />
<br />
<br />
====Craters====<br />
[[File:KerbinCraterElevation.jpg|thumb|left|Terrain model centered on one of Kerbin's most pronounced craters]]<br />
Unlike other bodies in its system, Kerbin has few visible craters because its environment would erode craters from the few meteors that avoid the gravity or surface of its large moon and survive reentry. Nevertheless, some geological formations indicate that bodies have violently collided with Kerbin: two planetary features appear to be impact craters that are coincidentally separated by nearly 180 degrees. The least eroded, and therefore presumably youngest, of the two (both are in excess of 100 km diameter) lies along the coastline. The uplift is easily visible as a series of islands, and the feature has a central peak that pokes up through the water. The other, and older of the two, is near the prime meridian in the northern hemisphere and is more easily missed, but its uplift rims are visible, and it has a central rebound peak.<br />
<br />
== Atmosphere ==<br />
<!-- SPECULATION: Kerbin has an atmosphere of unknown composition, though Kerbin's plants and animals would not survive without O<sub>2</sub>, N<sub>2</sub>, and CO<sub>2</sub>. -->Kerbin's [[atmosphere]] contains oxygen and extends to roughly 69,078 meters. Its atmosphere exponentially rarefies with altitude (with a scale height of 5 km).<ref>{{forum link|threadID=16000|threadName=&#91;KGSS&#93; Examining Kerbin's atmosphere}}</ref> The atmospheric pressure on Kerbin at an altitude expressed in meters, generally is:<br />
<br />
: <math>p_k = e^{-altitude/5000}</math><br />
<br />
The thickness of Kerbin's atmosphere makes it suitable for [[aerobraking]] and using [[parachute]]s to save fuel during reentry. Debris is not affected by air resistance above approximately 10 km: spent stages may continue in a stable orbit even if they are going through thick atmosphere that would stop an active craft (0.19). Crafts will experience harmless re entry and supersonic air effects as of 0.19.<br />
<br />
The following table gives approximation of terminal velocities at different Kerbin altitudes, which are also the velocities at which a ship should travel for a fuel-optimal vertical ascent from Kerbin, given the game's model of atmospheric drag.<ref>http://forum.kerbalspaceprogram.com/showthread.php/6664-Mini-challenge-max-altitude-with-this-supplied-spacecraft?p=100912&viewfull=1#post100912</ref> The optimal velocity after a [[gravity turn]] has been started is less than the corresponding value in the table. <ref>http://www.reddit.com/r/KerbalSpaceProgram/comments/1kov5z/a_handy_chart_i_made_for_the_most_efficient/cbrdvuo</ref><br />

== Topography ==<br />
[[File:Kerbin_heightmap.jpg|thumb|left|Topographical representation of Kerbin's surface as of .18.2. Click for high resolution. by Zeroignite]]<br />
Kerbin has a roughly equal distribution of surface liquid water and solid land, with polar icecaps and scattered deserts. Some of its mountains exceed 6 km in height, with the tallest peak being 6761 m in altitude.<br />
<br />
<br />
====Craters====<br />
[[File:KerbinCraterElevation.jpg|thumb|left|Terrain model centered on one of Kerbin's most pronounced craters]]<br />
Unlike other bodies in its system, Kerbin has few visible craters because its environment would erode craters from the few meteors that avoid the gravity or surface of its large moon and survive reentry. Nevertheless, some geological formations indicate that bodies have violently collided with Kerbin: two planetary features appear to be impact craters that are coincidentally separated by nearly 180 degrees. The least eroded, and therefore presumably youngest, of the two (both are in excess of 100 km diameter) lies along the coastline. The uplift is easily visible as a series of islands, and the feature has a central peak that pokes up through the water. The other, and older of the two, is near the prime meridian in the northern hemisphere and is more easily missed, but its uplift rims are visible, and it has a central rebound peak.<br />
<br />
== Atmosphere ==<br />
<!-- SPECULATION: Kerbin has an atmosphere of unknown composition, though Kerbin's plants and animals would not survive without O<sub>2</sub>, N<sub>2</sub>, and CO<sub>2</sub>. -->Kerbin's [[atmosphere]] contains oxygen and extends to roughly 69,078 meters. Its atmosphere exponentially rarefies with altitude (with a scale height of 5 km).<ref>{{forum link|threadID=16000|threadName=&#91;KGSS&#93; Examining Kerbin's atmosphere}}</ref> The atmospheric pressure on Kerbin at an altitude expressed in meters, generally is:<br />
<br />
: <math>p_k = e^{-altitude/5000}</math><br />
<br />
The thickness of Kerbin's atmosphere makes it suitable for [[aerobraking]] and using [[parachute]]s to save fuel during reentry. Debris is not affected by air resistance above approximately 10 km: spent stages may continue in a stable orbit even if they are going through thick atmosphere that would stop an active craft (0.19). Crafts will experience harmless re entry and supersonic air effects as of 0.19.<br />
<br />
The following table gives approximation of terminal velocities at different Kerbin altitudes, which are also the velocities at which a ship should travel for a fuel-optimal vertical ascent from Kerbin, given the game's model of atmospheric drag.<ref>http://forum.kerbalspaceprogram.com/showthread.php/6664-Mini-challenge-max-altitude-with-this-supplied-spacecraft?p=100912&viewfull=1#post100912</ref> The optimal velocity after a [[gravity turn]] has been started is less than the corresponding value in the table. <ref>http://www.reddit.com/r/KerbalSpaceProgram/comments/1kov5z/a_handy_chart_i_made_for_the_most_efficient/cbrdvuo</ref><br />

The thickness of Kerbin's atmosphere makes it suitable for [[aerobraking]] and using [[parachute]]s to save fuel during reentry. Debris is not affected by air resistance above approximately 10 km: spent stages may continue in a stable orbit even if they are going through thick atmosphere that would stop an active craft (0.19). Crafts will experience harmless re entry and supersonic air effects as of 0.19.<br />

The following table gives approximation of terminal velocities at different Kerbin altitudes, which are also the velocities at which a ship should travel for a fuel-optimal vertical ascent from Kerbin, given the game's model of atmospheric drag.<ref>http://forum.kerbalspaceprogram.com/showthread.php/6664-Mini-challenge-max-altitude-with-this-supplied-spacecraft?p=100912&viewfull=1#post100912</ref> The optimal velocity after a [[gravity turn]] has been started is less than the corresponding value in the table. <ref>http://www.reddit.com/r/KerbalSpaceProgram/comments/1kov5z/a_handy_chart_i_made_for_the_most_efficient/cbrdvuo</ref><br />

<div>{{:Eeloo/Data}}<br />
<br />
'''Eeloo''' is a [[w:dwarf planet|dwarf planet]] that was released in {{version|0.18.2}} as a Christmas gift to the KSP community. It is the seventh and farthest planet from [[Kerbol]] most of the time, though its orbit intersects [[Jool]]'s, passing in front of it for a minority of its revolution period. The two planets are locked in a 3:2 resonance, which, coupled with their different inclinations, ensures they cannot collide.<br />
<br />
Eeloo has just 3.5% more gravity than the [[Mun]] and is very similar in size. Like the Mun, it has no atmosphere. The physical characteristics of Eeloo are most likely an analogue of the ice moon [[w:Enceladus (moon)|Enceladus]], and its orbit is similar to that of [[w:Pluto (dwarf planet)|Pluto]], though both bodies are known to have a tenuous atmosphere.<br />
<br />
== Topography ==<br />
The surface of Eeloo is relatively smooth and covered in ice, with deep canyons exposing the surface below. The highest points are near the equator and are almost 3.9 km high. The lower areas can go lower than sea level<br />
<br />
== Orbits ==<br />
Eeloo's far and large orbit makes it a challenge to successfully make an encounter with the celestial body.<br />
<br />
A synchronous orbit around Eeloo is possible, at an altitude of ~683.9 km. <br />
<br />
== Communication ==<br />
Using the Remote Tech plugin, path lengths from Kerbin can reach up to around 127 [[w:gigametre|Gm]] (127 billion meters), resulting in a round trip delay longer than 14 minutes. Even at the closest approach, the communication delay is more than 6 minutes.<br />
<br />
== Planned Features ==<br />
There are plans for Eeloo to become the moon of a second gas giant and have an active surface, with ''cryovolcanic'' phenomena.<ref>http://forum.kerbalspaceprogram.com/showthread.php/35829-Eeloo-Discussion!?p=398040&viewfull=1#post398040 (outdated link)</ref> It is unknown what Eeloo's parent planet will look like.<br />

<div>{{:Vall/Data}}<br />
<br />
'''Vall''' is one of the five [[w:Natural_satellite|natural satellites]] of [[Jool]]. Like the other large Joolian moons, Vall is tidally locked. Synchronus orbits around Vall are not possible, as they would lie outside of its SOI, at a radius of 3,893,254 meters.<br />
<br />
Vall is KSPs analog to Jupiter's moon [[w:Europa_%28moon%29|Europa]].<br />
<br />
Landing on Vall and returning is significantly more challenging than the [[Mün]]. It lacks atmosphere but has a higher gravity and more uneven terrain, so a larger rocket is required.<br />
<br />
== Topology ==<br />
<br />
It has an icy surface which is dominated by hilly lowland areas separated by mountain ridges, ranging in elevation from 0 m to 7976 m. There are almost no completely level areas, making it hard to find good landing spots. <br />
<br />
Vall has some circular mountain ridges which could be remnants of impact craters, but they are heavily eroded, hinting that Vall has some geological activity, pressumably in form of cryovolcanism.<br />
<br />
The surface color ranges between white and light-blue. When terrain scatters are activated, large boulders with contrast-rich black and white surface patterns can be found on the surface.<br />

'''Eeloo''' is a [[w:dwarf planet|dwarf planet]] that was released in {{version|0.18.2}} as a Christmas gift to the KSP community. It is the seventh and farthest planet from [[Kerbol]] most of the time, though its orbit intersects [[Jool]]'s, passing in front of it for a minority of its revolution period. The two planets are locked in a 3:2 resonance, which, coupled with their different inclinations, ensures they cannot collide.<br />
<br />
Eeloo has just 3.5% more gravity than the [[Mun]] and is very similar in size. Like the Mun, it has no atmosphere. The physical characteristics of Eeloo are most likely an analogue of the ice moon [[w:Enceladus (moon)|Enceladus]], and its orbit is similar to that of [[w:Pluto (dwarf planet)|Pluto]], though both bodies are known to have a tenuous atmosphere.<br />
<br />
== Topography ==<br />
The surface of Eeloo is relatively smooth and covered in ice, with deep canyons exposing the surface below. The highest points are near the equator and are almost 3.9 km high.<br />
<br />
== Orbits ==<br />
Eeloo's far and large orbit makes it a challenge to successfully make an encounter with the celestial body.<br />
<br />
A synchronous orbit around Eeloo is possible, at an altitude of ~683.9 km. <br />
<br />
== Communication ==<br />
Using the Remote Tech plugin, path lengths from Kerbin can reach up to around 127 [[w:gigametre|Gm]] (127 billion meters), resulting in a round trip delay longer than 14 minutes. Even at the closest approach, the communication delay is more than 6 minutes.<br />
<br />
