A planet's mass will pull every ship in a certain distance towards the planet (default: 3 ly). This can be used to save fuel: move just to the edge of the warp well and let the planet pull you. To move inside a warp well, you must go at Warp 1; Warp 1 ships are not pulled.

This is a testing version.
It may be incomplete, and have more bugs (or features) than the public live version at planetscentral.com.
