Planet Wiki is a mini-wiki that is based off of the KSPedia system that Squad
put into the game. It contains information regarding the planets and moons such
as science multipliers in different situations, and also the border altitude
between different situations like "In Space High" vs. "In Space Low".

So far the pages are populated with the following information:

A picture of the planet
Pictures of the planet's parent body and moons
The planet's in-game description
The science multiplier in different situations at the planet
The altitude border between different situations at the planet
Orbital Period
The planet's orbital inclination
Semi-major axis needed for synchronous orbit
The phase angle for optimal transfer
delta-v needed to (safely) get to the surface from Kerbin's surface
delta-v needed to land/take off
delta-v needed to escape
Surface gravity in g's
Height of the atmosphere
Number of biomes
The highest and lowest point on the surface, with their coordinates
The Sidereal day length
Efficiency of solar panels on planet's surface (as opposed to Kerbin's surface)
Minimum and maximum distances that the planets can be from Kerbin
The radius of each body.
