<br />
[[Kerbol]] (officially called '''the Sun''', and also known as '''the Star''') is the central star of the '''[[Kerbol System]]'''. Five planets are known to orbit it: '''[[Moho]]''', '''[[Eve]]''', '''[[Kerbin]]''', '''[[Duna]]''' and '''[[Jool]]''' and two dwarf planets '''[[Eeloo]]''' and '''[[Dres]]'''.<br />
<br />
Compared to our own [[w:Sun|Sun]], Kerbol has a 113 times lesser mass and 3 time smaller radius. Kerbol's other attributes can be used to make the following comparisons: It has the temperature of a [[w:K-type_main-sequence_star|K Class main sequence star]], the radius of a [[w:Red_dwarf|M class star]], the luminosity of a [[w:G-type_main-sequence_star|G class star]], and the mass of a [[w:Sub-brown_dwarf|sub-brown dwarf]]. In reality, such a star cannot exist as the minimum mass of a star is approximately 75 times the mass of Jupiter, a full power of ten higher than that of Kerbol.<br />
<br />
== Orbiting Kerbol ==<br />
Orbits just above the surface have an orbital period of 409.214 minutes and a speed of 66.945 km/s.<br />
<br />
While Kerbol can be reached from [[Kerbin]]'s orbit by using a [[Mun Landing#Step 2 - To The Mun|Hohmann transfer orbit]], doing so requires a Δv of about 8 km/s. The most efficient way to reach Kerbol from Kerbin orbit is to use a [[Tutorial:_Advanced_Orbiting#Bi-Elliptical_Transfer|bi-elliptic transfer]]. With a sufficiently-distant apoapsis, the required ΔV to sundive can be reduced to under 4 km/s at the expense of drastically-increased flight time.<br />
<br />
The [[sphere of influence]] of Kerbol is infinite. A orbit around Kerbol is inescapable, and achieving gravitation-free flight is impossible. Once the apoapsis reaches a certain point, the game will say that it 68 years to reach. This oddity occurs because times in Kerbal Space Program are limited to 2<sup>32</sup>-1 seconds as a consequence of how numbers are handled.<br />
<br />
== Physical appearance ==<br />
The equatorial radius of Kerbol is almost four times that that of Jupiter and 43.6 times larger than Jool's radius, currently the largest known planet. <!-- Jupiter's radius is about 67 000 km, Kerbol's radius is about 3.8 times greater --> Kerbol's heat will always destroy a [[craft]], even with the "No crash damage" [[cheat]] enabled, and makes landing on Kerbol impossible.<br />
<br />
Squad has long-term plans for solar flares and prominences that would make a low Kerbol orbit even more dangerous.{{cn}} <!-- is this statement speculation, or an actual plan of the devs? --> Since 0.14, the “surface” of Kerbol is an invisible and nearly featureless plateau that stands approximately 4500-4700 km<sup>[''[[Talk:Kerbol#Outdated_Surface_height|dubious]]'']</sup> above the nominal radius. No known way of landing on it exist because the [[Kraken]] impedes maneuvering, and the gravity reduces the [[thrust-to-weight ratio]] of all engines to below 1.<sup>[''[[Talk:Kerbol#All_engines_have_a_TWR_below_1_at_the_surface.3F|dubious]]'']</sup> One can attempt to place edited parts on the surface, but they bounce erratically at a few hundred to a few thousand m/s if they do not explode.<br />
<br />
Until version 0.11 Kerbol was a point of light in the skybox impossible to reach, although no “surface” existed. Up to version 0.13.3 dropping below the “surface” was still safe, but a ship can break up from the extreme gravity gradients and/or be shot outwards at large fractions of the speed of light.<br />
<br />
If you are close enough, you can see the dark spots are indented in Kerbol<br />
<br />
== Reference Frames ==<br />
{{:Kerbol/RefFrame}}<br />
All Kerbol orbits are in an inertial reference frame. In the old demo, getting close enough to experience the lower maximum time warps results [[Deep Space Kraken]] attacks.<br />
<br />
== Trivia ==<br />
* The name “Kerbol” was created by forum members and never appears in the game. Officially, the star is simply referred to as “the Sun," though the lead developer mentioned that its name could change once the need to differentiate it from other stars arises.<br />
* Kerbol has just under twice the surface gravity of Kerbin, but only slightly more than Eve.<br />

'''Jool''' is a [[w:Gas giant|gas giant]] and the sixth planet of the [[Kerbol]]ar star system. It is the most distant of the six planets and the hardest to reach. It is one of the most appealing targets for missions, however, because of its large and complex system of five moons: '''[[Laythe]]''', '''[[Vall]]''', '''[[Tylo]]''', '''[[Bop]]''', and '''[[Pol]]'''. Orbits well-aligned with the orbital plane, and many intersections with moon orbits can easily be captured by a couple moons with little to no ΔV before having to correct your orbit.<br />
<br />
== Atmosphere ==<br />
{|<br />
|<br />
[[File:JoolAtmosphere.png|thumb|right|Aerobraking in Jool's atmosphere.]]<br />
<br />
Although Jool has a radius ten times greater than [[Kerbin]], its [[atmosphere]] begins just twice as high (138.2 km). It is extremely dense, well suited for aerobraking from a high-speed interplanetary intercept. Orbiting just outside the atmosphere will give you a period of 94.7437 minutes, and a speed of 6,785 m/s. You typically do not need to go lower than 60 km to aerobrake.<br />
<br />
In general, the atmospheric pressure on Jool at an altitude expressed in meters is:<br />
: <math>p_j = 15\ e^{-altitude/9000}</math><br />
<br />
Closer to the surface, the physics of the game start to break down. Due to its extremely thick atmosphere, terminal velocity is so low that lighter spacecraft will not even need parachutes or retrorockets. It is not impossible to land on its solid surface, though spacecraft are inevitably and invariably devoured by the [[Kraken]]. If a kerbonaut is put on EVA he will not be destroyed, making one-way sacrificial landings feasible.<br />

[[File:JoolLaythe.png|thumb|right|The ocean moon [[Laythe]], about to transit Jool.]]<br />
<br />
Jool has five natural satellites:<br />
* The ocean moon [[Laythe]], currently the only moon possessing an atmosphere, is the closest to Jool and second largest of its moons. Due to its high orbital velocity, it is somewhat challenging to reach. Next to [[Eve]], it's size and composition make it the most similar celestial body to [[Kerbin]]<br />
* The ice moon [[Vall]], which is the third largest and second closest. Its orbital path and velocity sit almost exactly between Layth and Tylo.<br />
* The rocky moon [[Tylo]], similar to Kerbin's [[Mun]], although it has similar gravity to [[Kerbin]]. It is the third and largest body orbiting Jool, and is perhaps the easiest of the five to reach, with a stable orbit, large gravity well, and (relatively) slow orbital velocity.<br />
* The captured asteroid [[Bop]], the smallest body orbiting Jool. Due to its distant, erratic orbit and low gravity, it is also challenging to reach.<br />
<br />
*In 0.18, a new moon was added, Pol, named so after a Pollen grain which it resembles. A yellowish/greenish moon, rocky and uneven with tall spiky mountains. It orbits Jool beyond Bop and is around twice as large. An image can be found [http://i.imgur.com/SshEN.png here].<br />
<br />
Laythe, Vall, and Tylo are in a Laplace resonance, with orbital periods of 1:2:4 respectively. Despite the fact that the moons can easily eclipse both each other and Jool, they do not.<br />

<br />
The '''Basic Jet Engine''' is an air-breathing engine which can use liquid fuel from the C7 fuselages or FL-T fuel tanks.<br />
<br />
== Usage ==<br />
Unlike rocket engines, a jet draws oxidizer from the atmosphere rather than taking it from an on-board tank. This is represented in-game by a much lower rate of fuel consumption. This engine cannot function effectively at a height of much more than 5km, but it is much more efficient to use jet engines in the lower atmosphere. Jets control a little differently to the rocket engines. The fan in front takes time to change speed, and if the throttle is too low the engine will stall. By contrast, rocket engines give instant response to your control input.<br />
<br />
The basic jet engine works at full power on the ground, whereas the [[TurboJet Engine]] won't get up to full power until you're over a kilometer up. However, the turbojet is so much stronger that this advantage doesn't add up to much, and when you consider that the turbojet works at more than twice the altitude there really isn't any reason not to take it instead, as of KSP v0.15.<br />
<br />

<br />
The '''TurboJet Engine''' is an air-breathing engine which requires fuel from FL-T fuel tanks.<br />
<br />
== Usage ==<br />
The TurboJet Engine uses a fan to draw oxygen from the atmosphere rather than from an onboard tank like a rocket engine, which makes it far more fuel-efficient than any rocket motor at altitudes below twelve kilometers. However, the TurboJet's fan is problematic: fly above twelve kilometers or at low throttle and it will draw too little air, moreover, the fan itself takes time to adjust to new power settings whereas a rocket motor responds instantly to throttle input.<br />
<br />
The Turbojet might not like breathing in thick atmosphere, but it's sufficiently powerful that using the [[Basic Jet Engine]] at low altitudes provides little improvement.<br />
<br />
In real life, a turbojet engine's fan pulls all the air from the intake through a combustion chamber, as opposed to a turbofan in which some of the air sucked in bypasses the chamber and is shot out of the back without being burned at all. The turbojet is more efficient at high speeds and in thinner atmospheres, although turbofans are much quieter and are very efficient when moving slowly. This is why turbofans are almost exclusively fitted on airliners, and turbojets are more common on fighter planes.<br />
<br />
== Description ==<br />
{{Quote<br />
