Planets
As of version 0.15 there is only a single orbiting planet, Kerbin. Additional planets are planned for future versions.

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.
