Mobile World
A Mobile World is a world capable of moving under its own power. Essentially, a planet or planetoid that is a spaceship; alternately, a spaceship large enough to qualify as a world. Does not have to be a starship, though those are not disqualified.
Description (Specifications)
The exact cutoff varies, but there is general agreement that merely using a planetoid as a spaceship hull is insufficient. The defining characteristic is size or mass. A planetoid hull spaceship with a diameter of 500 kilometers (the dividing line between "planetoid" or "planet") would certainly qualify, while one with a diameter of only 1.0 kilometer would not, according to most sources.
Planetary Characteristics
There are two competing schools of thought regarding mobile worlds.
- One postulates that, if they existed, they would be more spaceship than world, and would generally be laid out like the largest civilian ships known, just much larger. (It is difficult to imagine a military purpose for such a large ship, other than destroying entire worlds, which seems too inefficient and wasteful for a civilization capable of building such a titanic object.)
- The other boils down to, "start with world, add massive engines", suggesting that the majority of the architecture would be whatever the world was prior to being made mobile; this has been depicted numerous times as a feature added to a tent world, with some heat and light source to sustain life on the planet when it is removed from its original system.
In both cases, a lack of known examples leads to speculative design.
Probably Planetary Orbit & Climate
Not applicable. By definition, a mobile world could insert itself into any orbit its crew desired, and presumably would be able to generate its own climate.
History & Background (Dossier)
There are many legends, rumors, and the odd Old Spacer's Tale of mobile worlds, as well as fictional portrayals. As of 1105 there are no proven and documented instances in Charted Space, though there have been observations of certain other parts of the galaxy which could be explained by the presence of one ore more mobile worlds (...among other theories).
