| − | '''קרבול''' (הנקרא באופן רשמי '''השמש''', וידוע גם בשם '''הכוכב''') הוא הכוכב במרכז [[Kerbol System/he|מערכת קרבול]]. ידוע שמקיפים אותו חמישה כוכבי לכת: בקיצור [[מוהו]], [[איב]], [[Kerbin/he|קרבין]], [[דונה]] ו[[ג'ול]] ושני כוכבי לכת ננסי [[אילו]] ו[[דרז]]. בהשוואה
| |
| − | בהשוואה ל [http://he.wikipedia.org/wiki/%D7%94%D7%A9%D7%9E%D7%A9 שמש] שלנו, קרבול הוא פי 113 פחות מסיבי והרדיוס שלו קטן פי שלוש. [http://he.wikipedia.org/wiki/%D7%A1%D7%99%D7%95%D7%95%D7%92_%D7%A1%D7%A4%D7%A7%D7%98%D7%A8%D7%9C%D7%99 תכונות נוספות] של קרבול יכולות לשמש להשוואות נוספות: יש לו את הטמפרטורה המתאימה לכוכב מסוג K , רדיוס המתאים לננס אדום, בהירות של בערך 3 יוטה-וואט לפי הטמפרטורה על פני קרבין, ומסה המתאימה לתת-ננס חום. במציאות, כוכב שכזה לא יכול להתקיים מכיוון שהמסה המינימלית של כוכב היא בערך פי75 ממסת כוכב הלכת צדק, מספר זה הוא פי עשר ממסת קרבול. חשוב לציין שתכונות אסטרופיזיקליות רבות מונמכות עבור המשחק.

| |
| − | 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.

| − | == Trivia ==
| |
| − | * בין הגירסאות 0.7 ל-0.10, Kerbol הייתה רק נקודת אור בשמיים.
| |
| − | * Kerbol gained gravity in 0.12.
| |
| − | * It is still safe to drop below the 'surface' in 0.13.3, but a ship can break up from the extreme gravity gradients and/or shot outwards at large fractions of c.
| |
| − | * Since 0.14, close encounters will result in a collision that destroys the ship and kills all crew members.
| |
| − | * The current “surface” of Kerbol is an invisible, and likely, featureless plateau approximately 4500–4700 km above the nominal radius. There is no known way to land on it, as the [[Kraken]] makes all maneuvering difficult, and the gravity reduces the TWR of all engines below 1. 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.
| |
| − | * While Kerbol can be reached from [[Kerbin|Kerbin's]] orbit by using a [[Mun Landing#Step 2 - To The Mun|Hohmann transfer orbit]], a spacecraft doing so will require a ΔV of about 8 km/s to do so. The most efficient way to reach Kerbol from [[Kerbin|Kerbin's]] 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.
| |
| − | * 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 did mention that the name could change once the need to differentiate it from other stars arises.
| |
| − | * Kerbol's Sphere of Influence is infinite, which makes it impossible to escape its orbit and achieve gravitation-free flight.
| |
| − | * Once the sun apoapsis reaches a certain point, it will always say it takes 68 years to reach. This is because times in Kerbal Space Program are limited to 2<sup>32</sup>-1 seconds as a consequence of how numbers are handled.
