Rheales and Azarthea

AZARTHEA AND RHEALES
Azarthea is the larger planet in a twin dwarf planet system orbiting far around the binary stars, Aur and Kesef. Both planets are mainly composed of sulphuric silicate; both are covered with an ocean of liquid nitrogen. Azarthea's landscape consists mostly of steep ridges protruding sparsely from the ocean surface, whereas Rheales' landscape is mostly flat, characterized by more beaches and shallow expanses.
