selene

The moonlet Selene, named after Earth’s moon, is Auraxis’ only major natural satellite, and a subsatellite to Doramir.

Falling perilously close to the extent of Auraxis’ Hill Sphere, the small moon, a mere 600 km in diameter, is not especially noteworthy. A basic planetoid composed primarily of silica and other light compounds, the world’s geology is nearly identical to that of Earth’s moon, with the exception that it does not appear to have dark “seas” of hardened basaltic lava.

Combined with the moon’s extremely unusual orbit around Auraxis and lack of mare, it is likely that it was captured gravitationally by the strange spacetime anomalies emanating from the Auraxian core some time after it was formed and solidified.
