(the whole section seems confused, it's conflating real world and KSP notions. there's no mystery; KSP just doesn't have the astrophysical phenomena that one would call an "edge" of a solar system, Kerbol is a point mass)

Orbits of planets and dwarf planets
All celestial bodies orbiting Kerbol with the sizes to scale
Comparison of the radii

The Kerbol System is the planetary system in which Kerbal Space Program takes place, as well as the first explorable planetary system in Kerbal Space Program 2. 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.

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 an 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)
