Hard data on Wentania is very limited. When the system was charted by the Alliance surveyor Kupe, only a small, unmanned flyby probe was spared for the distant world. It is a small rock and ice planet, with a trace atmosphere of krypton and sulphur dioxide. Normandy's more detailed survey suggests the frozen terrestrial may be suitable target for mining. While it is largely water ice, mapping of mass concentrations suggests it has a core of pure aluminium.
