Nyx III

The final planet in the Nyx System, located far from the sun's light, is an ice giant. A massive ball of frozen water and ammonia vapor, Nyx III is neither a candidate for terraformation nor one that contains any minerals or other resources worth extracting. The planet has no breathable atmosphere. While a ship with an onboard life support could itself survive for a time on the surface, there is little reason to attempt such a feat. EVA would be impossible, and external ship repair would likely be easier in a vacuum.
