Nyx II

A smoggy, desolate world, Nyx II was once considered an edge case for terraforming. Thick clouds of acid and carbon dioxide surround the world and the planet is technically teetering at the inner edge of the system's green band. Nevertheless, a serious study was conducted as to whether or not it could be made inhabitable. The end result was that it could, but it would take generations of effort and provide little reward beyond the creation of a base particularly well hidden by nebula gasses. EVA on the planet itself is lethal; even if explorers are protected from the corrosive elements, they will be unable to function in the high-pressure atmosphere.
