Almarcrux

Almacrux has an atmosphere of methane and ethane. Despite the distance from Caspian, the energetic, young star heats the surface to almost temperate levels. Thick ground fogs are common at the terminator, where frozen ice water from the long, cold, night side, meets the warm, air masses from the day side. The crust is mainly composed of sodium with deposits of copper. Almacrux's abundant water and relatively mild temperature and gravity have put the planet on the short list for terraforming. However, there is significant opposition from eco-ethics groups who assert that the methane-based bacteria in the atmosphere are the precursors to a full-fledged ecology.
