The most convenient route from Earth to Pandora: on an A-class starship toward the Alpha Centauri A star system.
The distance is 4.37 light-years from Earth. It is one of many natural satellites orbiting the gas giant Polyphemus.
The flight takes a little over a week, given the acceleration and deceleration of the warp drive of any modern starship.
There are regular shuttles from the Apex orbital station to the Hansa Spaceport, which is connected to the airport of the same name, from where you can book a transfer by our screenplane.
