Rocky Dwarf Planet
Greab is the furthest notable natural body from Hyperbrasil A. It is a small dwarf planet that is green in color. This is its only notable trait. It is otherwise entirely uninteresting. It has no geological activity and is rounded under its own gravity. Greab has little valuable resources, except on its surface, which is covered in a thin layer of jade. It is not worth harvesting due to the amount of time and fuel required for travel between Greab and any market.
Greab has a single permanent base, inhabited by the occasional visiting scientists. The base's only permanent inhabitants are Michael G. Reeve (Homo Sapiens) and a small colony of rats (Rattus Sapiens). Reeve lays claim to the entire dwarf planet. His claim is not contested by any governing body.
