'''Kerbol''' (officially called '''the Sun''' and sometimes '''the Star''') is the parent star of the [[w:Planetary system|planetary system]] in KSP, popularly referred to as the '''[[Kerbol System]]'''. As of {{version|0.23.5}}, it has seven known children: the planets '''[[Moho]]''', '''[[Eve]]''', '''[[Kerbin]]''', '''[[Duna]]''' and '''[[Jool]]''' and the two dwarf planets '''[[Dres]]''' and '''[[Eeloo]]'''.

'''Kerbol''', A.K.A. the Sun, is the parent star of the '''[[Kerbol System]]''', making it the core of the explorable [[w:Planetary system|planetary system]] in [[KSP1]], as well as the first explorable planetary system in [[KSP2]]. Five planets: '''[[Moho]]''', '''[[Eve]]''', '''[[Kerbin]]''', '''[[Duna]]''' and '''[[Jool]]'''; and two dwarf planets: '''[[Dres]]''' and '''[[Eeloo]]'''; orbit around it. Kerbol contains 99.97% of the mass in the Kerbol system. This is very similar to our sun which contains 99.86% of the mass in the real world solar system.

While otherwise analogous to our own real-life [[w:Sun|Sun]], Kerbol has 113 times less mass and a 3 times smaller radius. Kerbol's other attributes can be used to make the following comparisons: it has a luminosity of approximately 3 Yotta-watts based on planet Kerbin's temperature (0.01 Solar luminosities), a surface temperature of approximately 2800 K based on its size and luminosity—the temperature of a [[w:Stellar_classification#Class_M|M Class main sequence star]], the radius of a [[w:Red dwarf|red dwarf]], 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. However, many astrophysical properties in KSP are effectively scaled down. Kerbol's [[w:Absolute_magnitude|absolute bolometric magnitude]] is +10.
+
"Kerbol" was originally a fan-made portmanteau of "Kerbal" and "Sol" — the Latin name for the real-life [[w:Sun|Sun]]. Before {{version|0.11}} of KSP1, which introduced an object for Kerbin's parent star and an orbital [[Map view]] where it was explicitly named, it was an unnamed directional light source at infinite distance. Fans on the KSP forums invented and popularized the name, and the term "Kerbol System" was used in the official 1.2 release post, the first issue of "The Kerbal Chronicles" as well as in the official trailer for the KSP Enhanced Edition. Doing an ice chunk analysis on Eeloo can confirm this name in KSP1. In KSP2, the star is explicitly named "Kerbol".

Escaping the SOI of any other body will place an object in orbit around the Sun (Kerbol). This will give a [[Science]] situation of being in space high over the Sun (Kerbol) until an altitude less than 1,000 Mm is reached. Low orbit can be reached by using a standard [[Tutorial: Advanced Orbiting#Hohmann transfer|Hohmann transfer]] from [[Kerbin]]'s orbit, this requires about 8 km/s of change-in-velocity (Δv). The more efficient way to reach low Sun (Kerbol) orbit, at the expense of drastically increased flight time, is to use a [[Tutorial: Advanced Orbiting#Bi-elliptical transfer|bi-elliptical transfer]]. With a sufficiently-distant apoapsis, the required Δv to "sundive" from Kerbin orbit can be reduced to under 4 km/s.

Previously the closest sustained altitude was 1,340 m, but now bodies emit radiation which heats parts and overheats parts before it could reach the atmosphere. The heating varies on the surface area it shines and part specific heat. Using parts with higher maximum temperature reduces the chance of [[overheating]], making the inflatable heat shield a good choice to shield your delicate parts from heat. This imposes a challenge where the objective is to get as close to the Sun as possible while surviving.

The [[sphere of influence]] (SOI) of the Sun (Kerbol) is infinite, making the Sun (Kerbol) inescapable. Thus, achieving gravitation-free flight is impossible. With a powerful enough ship, it is possible to get to the point where the info tab will display the craft's situation as "escaping" the Sun (Kerbol). The end of the patched conics path plotted by the game can be reached, at which point the spacecraft begins drawing a course behind it. But the actual escape never occurs. Presumably, this state would continue indefinitely, as the time required to find out what would happen would take several years real-time even at maximum time acceleration.

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.
+
Similar to [[Jool]], it's impossible to land on the Sun. Any objects are destroyed at an altitude below -250 m, which shows in the end flight dialog as "crashed into the surface of the sun" or similar, rather than ever landing.
  
−
Orbits just above the surface have an orbital period of 409.214 minutes and a speed of 66.945 km/s. At around 1,340m above the surface, there is a sudden increase in temperature which causes destruction to vessel parts and [[kerbonaut]]s on [[Extra-Vehicular Activity|EVA]]; this marks the closest sustained altitude possible, though catastrophic dives to lower depths are possible.

One can attempt to place edited parts on the surface, but they bounce erratically at a few hundred to a few thousand meters per second if they do not explode.
  
−
The [[sphere of influence]] of Kerbol is infinite. An 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 takes 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.

[[File:Kerbol_temperature.png|thumbnail|left|Temperature-height profile of Kerbol's atmosphere.]]

The Sun's (Kerbol's) visible surface, its [[w:Photosphere|photosphere]], has a temperature of 5840&nbsp;K. This temperature, along with the star's yellow color, suggests that the Sun (Kerbol) is a [[w:G-type_main-sequence_star|Class G main-sequence star]]. Above the photosphere is a thin and hot atmosphere that is analogous to a [[w:Chromosphere|chromosphere]]. The chromosphere extends to a height of 600&nbsp;km and has at its base a pressure of 16&nbsp;kPa. The temperature of the chromosphere decreases with increasing altitude until reaching a minimum of 4000&nbsp;K at a height of 50&nbsp;km. Above 50&nbsp;km the temperature increases with increasing altitude. The maximum temperature of 10,000&nbsp;K is reached at the atmosphere's extreme upper limit.
  
−
With a powerful enough ship, it is possible to get to the point where one is "escaping" Kerbol. This can easily be achieved (as of 0.23.5). While the actual escape never occurs, the info tab will display the craft's situation as "escaping". It will reach a point where the course plotted by the game ends, and the spacecraft begins plotting its own course. Presumably, this will continue indefinitely, as the time required to find out what would happen would take several years.
+
Based on its given size and temperature, the Sun's (Kerbol’s) luminosity would be 56.7 yottawatts, however this is contradicted by other in-game physical parameters. The value of the solar constant at Kerbin is 1360 W/m<sup>2</sup>, which implies a solar luminosity of 3.16 yottawatts (0.008 Solar luminosities) and a surface temperature of 2840&nbsp;K. These values are consistent with a [[w:Red dwarf|Class M red dwarf]].

Kerbol, A.K.A. the Sun, is the parent star of the Kerbol System, making it the core of the explorable planetary system in KSP1, as well as the first explorable planetary system in KSP2. Five planets: Moho, Eve, Kerbin, Duna and Jool; and two dwarf planets: Dres and Eeloo; orbit around it. Kerbol contains 99.97% of the mass in the Kerbol system. This is very similar to our sun which contains 99.86% of the mass in the real world solar system.

"Kerbol" was originally a fan-made portmanteau of "Kerbal" and "Sol" — the Latin name for the real-life Sun. Before version 0.11 of KSP1, which introduced an object for Kerbin's parent star and an orbital Map view where it was explicitly named, it was an unnamed directional light source at infinite distance. Fans on the KSP forums invented and popularized the name, and the term "Kerbol System" was used in the official 1.2 release post, the first issue of "The Kerbal Chronicles" as well as in the official trailer for the KSP Enhanced Edition. Doing an ice chunk analysis on Eeloo can confirm this name in KSP1. In KSP2, the star is explicitly named "Kerbol".

In-game description

“ The Sun is the most well known object in the daytime sky. Scientists have noted a particular burning sensation and potential loss of vision if it is stared at for long periods of time. This is especially important to keep in mind considering the effect shiny objects have on the average Kerbal.

Gravitational influence

Escaping the SOI of any other body will place an object in orbit around the Sun (Kerbol). This will give a Science situation of being in space high over the Sun (Kerbol) until an altitude less than 1,000 Mm is reached. Low orbit can be reached by using a standard Hohmann transfer from Kerbin's orbit, this requires about 8 km/s of change-in-velocity (Δv). The more efficient way to reach low Sun (Kerbol) orbit, at the expense of drastically increased flight time, is to use a bi-elliptical transfer. With a sufficiently-distant apoapsis, the required Δv to "sundive" from Kerbin orbit can be reduced to under 4 km/s.

Previously the closest sustained altitude was 1,340 m, but now bodies emit radiation which heats parts and overheats parts before it could reach the atmosphere. The heating varies on the surface area it shines and part specific heat. Using parts with higher maximum temperature reduces the chance of overheating, making the inflatable heat shield a good choice to shield your delicate parts from heat. This imposes a challenge where the objective is to get as close to the Sun as possible while surviving.

The sphere of influence (SOI) of the Sun (Kerbol) is infinite, making the Sun (Kerbol) inescapable. Thus, achieving gravitation-free flight is impossible. With a powerful enough ship, it is possible to get to the point where the info tab will display the craft's situation as "escaping" the Sun (Kerbol). The end of the patched conics path plotted by the game can be reached, at which point the spacecraft begins drawing a course behind it. But the actual escape never occurs. Presumably, this state would continue indefinitely, as the time required to find out what would happen would take several years real-time even at maximum time acceleration.

Landing

Similar to Jool, it's impossible to land on the Sun. Any objects are destroyed at an altitude below -250 m, which shows in the end flight dialog as "crashed into the surface of the sun" or similar, rather than ever landing.

One can attempt to place edited parts on the surface, but they bounce erratically at a few hundred to a few thousand meters per second if they do not explode.

Temperature and luminosity

Temperature-height profile of Kerbol's atmosphere.

The Sun's (Kerbol's) visible surface, its photosphere, has a temperature of 5840 K. This temperature, along with the star's yellow color, suggests that the Sun (Kerbol) is a Class G main-sequence star. Above the photosphere is a thin and hot atmosphere that is analogous to a chromosphere. The chromosphere extends to a height of 600 km and has at its base a pressure of 16 kPa. The temperature of the chromosphere decreases with increasing altitude until reaching a minimum of 4000 K at a height of 50 km. Above 50 km the temperature increases with increasing altitude. The maximum temperature of 10,000 K is reached at the atmosphere's extreme upper limit.

Based on its given size and temperature, the Sun's (Kerbol’s) luminosity would be 56.7 yottawatts, however this is contradicted by other in-game physical parameters. The value of the solar constant at Kerbin is 1360 W/m2, which implies a solar luminosity of 3.16 yottawatts (0.008 Solar luminosities) and a surface temperature of 2840 K. These values are consistent with a Class M red dwarf.

Physical appearance

The equatorial radius of the Sun is almost four times than that of Jupiter and 43.6 times larger than Jool's, the largest planet known in the Solar (Kerbol) system. the Sun (Kerbol) has the yellow color of a Class G main-sequence star and its absolute bolometric magnitude is approximately +10. If close enough, one can see that the dark spots are indented.

The "corona" surrounding the Sun (Kerbol) is not the actual size of the sun as it appears. It will shrink and grow relative to the location of the viewpoint, just as the size of Kerbol does normally. However, it won't shrink past a certain point, and if the sun is viewed from a far enough point, the corona is still very visible. This is apparent when using camera or telescope mods that remove the corona and show the Sun's (Kerbol's) true size, which is usually much smaller than the corona appears.

Past appearances

Prior to version 0.11 there was only a nameless light in space.

version 0.7.3 introduced the parent star of Kerbin as a slightly red-tinted directional light (with lots of lens flare) in the skybox at infinite distance, thus impossible to reach.

Surface in version 0.17.

In version 0.11, it became a yellow sphere which could be visited but its surface wasn't solid. It was named "The Sun" in Map view; however, fans had already taken to calling the star "Kerbol". Up to version 0.13.3 dropping below the "surface" was still safe, but a ship could break up from the extreme gravity gradients and/or be shot outwards at large fractions of the speed of light.

Trivia

  • The Sun has just under twice the surface gravity of Kerbin, thus only slightly more than Eve's.
  • The Kerbal Sun is not a realistic analogue of our Real Sun.
    • The Mun is larger and closer to Kerbin than Moon to Earth, and thus in order to make eclipses work right, the Sun was made large enough to fit.

Real-world comparison

While otherwise analogous to our own real-life Sun, the Sun (Kerbol) has 1/113th the mass and 1/3rd its radius. The Sun's (Kerbol's) other attributes can be used to derive the following statistics: it has a luminosity of approximately 3 yottawatts based on the solar constant at Kerbin; a defined surface temperature of 5840 K (that of a Class G star), but a temperature less than 3000 K based on its size and luminosity (that of a Class M star); the radius of a red dwarf; and the mass of a sub-brown dwarf. Such a star in real life would be on the limits of Hydrostatic equilibrium and its small size would mean it would only generate as much heat as a red dwarf. However, many astrophysical properties in KSP are effectively scaled down for gameplay.

Its real-life counterpart according to its size and mass would be 2MASS J0523-1403, the smallest star currently known.
