All Kerbol orbits are in an inertial reference frame. Getting close enough to experience lower maximum time warps results in attacks by the Deep Space Kraken.
Planets
As of version 0.15 there is only a single orbiting planet, Kerbin. Additional planets are planned for future versions.
Also
Between 0.7 and 0.10.1, Kerbol was a mere point of light in the skybox. It became an possible to reach in 0.11, and gained gravity in 0.12. Since 0.14, close encounters will result in a collision that destroys the ship and kills all crew members. 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.
While Kerbol can be reached from Kerbin's orbit by using a Hohmann transfer orbit, a spacecraft doing so will require a delta-V 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 delta-V to sundive can be reduced to under 4km/s, at the expense of drastically-increased flight time.
The name "Kerbol" is created by the forum members, it never appears in the game. In the game the star is referred as "the Sun"
