The Kerbol System is the planetary system in which Kerbal Space Program takes place. It has Kerbol as the central body which is orbited by 5 planets and 2 dwarf planets. Only Kerbin and Laythe have an oxygen atmosphere and only Kerbin hosts life.
With the outermost dwarf planet Eeloo it reaches up to 113 549 713 200 m (about 113.5 Gm or 0.76 AU) out into space. Compared to our Solar System it is a very small system, as Earth's periapsis (or more specific perihelion) is about 147 Gm (or 0.98 AU) and thus outside of Eeloo's orbit.
It is difficult to determine if or where the Kerbol System has an edge. Kerbol itself has a non relativistic escape velocity, so it is possible to escape Kerbol. But itself it is not possible to escape Kerbol's gravitational pull, because the sphere of influence is infinite. Although real world gravity expands into infinity, it does only for Kerbol in KSP so it's unclear if this property can be used to determine where the edge is.

Planet from the Kerbol System are defined from a few characteristics:
| Characteristic | How the value was chosen |
|---|---|
| gravity at sea level | hand-picked, followed by a conversion from single to double precision (e.g. gravity on Eve is 1.70000004768372g instead of 1.7g) |
| radius | hand-picked, loosely a tenth the radius of its solar counterpart for Moho, Eve, Kerbin, Duna and Jool |
| rotational period | hand-picked or tidally locked, except Kerbin (21599.91201454015) and Duna (65517.859375) |
| orbit semi-major axis | a eleventh the one from its solar counterpart, except for Eeloo, computed in single precision floating point arithmetic |
| eccentricity | hand-picked, close to solar one for Moho, Jool and Eeloo |
| mean anomaly at epoch | hand-picked (radians), often 3.14 |
| inclination | hand-picked (degrees), close to solar one for Moho and Eve |
| longitude of ascending node | hand-picked (degrees) |
| argument of periapsis | hand-picked (degrees) |
