Idris I

Idris I is a terrestrial planet in the [Idris system](https://robertsspaceindustries.com/galactapedia/article/bZkrMGnLdM-idris-system), [United Empire of Earth (UEE)](https://robertsspaceindustries.com/galactapedia/article/VyvyKxy4v6-united-empire-of-earth). 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.
