Kerbol/Data

Kerbol (הנקרא באופן רשמי השמש, וידוע גם בשם הכוכב) הוא הכוכב במרכז מערכת Kerbol. ידוע שמקיפים אותו חמישה כוכבי לכת: בקיצור מוהו, איב, קרבין, דונה וג'ול ושני כוכבי לכת ננסי אילו ודרז.בהשוואה לשמש שלנו, הוא Kerbol 113 פעמים פחות מסיבי ויש לו 3 פעמים רדיוס קטן יותר. Kerbol צפוי כוכב ראשי מחלקת K רצף המבוסס על הטמפרטורה שלו, אבל זה גם יכול להיות כוכב כיתת ז מבוסס על הרדיוס שלו, או כוכב כיתת G מבוסס על הזוהר שלה.מקיף רק מעל פני השטח נותן תקופת ההקפה של 409.214 דקות ומהירות של 66.945 ק"מ / שני.

Compared to our own Sun, Kerbol is 113 times less massive and has a radius 3 times smaller. Kerbol is likely a K Class main sequence star based on its temperature, but it may also be an M class star based on its radius, or a G class star based on its luminosity.

Orbiting just above the surface gives an orbital period of 409.214 Minutes and a speed of 66.945 km/s.

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's orbit by using a 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's orbit is to use a 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 2³²-1 seconds as a consequence of how numbers are handled.
