Altaaya is an unusually large terrestrial world with a trade atmosphere of methane and ammonia. The surface is frozen, and mainly composed of sandstone and other sedimentary rocks with deposits of iron and chlorides. Judging by the sedimentary composition of the crust, it appears that Altaaya once possessed an atmosphere thick enough to support some form of liquid. What cataclysm stripped the atmosphere and left the planet to freeze is not currently known.
