Kerbol System
From Kerbal Space Program Wiki
The Kerbol System is at the moment the only available solar system. It has Kerbol as the central body which is orbited by 5 planets and 2 dwarf planets. Because the sphere of influence of Kerbol is infinite it is impossible to escape the system. 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.
