Idris I

Idris I is a terrestrial planet in the Idris system, United Empire of Earth (UEE). Closest in orbit to its system's sun, heat and radiation have eroded the planet's crust and mantle down to its solid iron core. Its surface is covered in extensive mare-like plains and heavy cratering. The largest of these craters has a diameter of roughly 1600 kilometers, and is surrounded on all sides by a concentric mountainous ring.
