The Sol(ar) system is the home star system of the human species, hosting their homeworld Earth. At its center is the G2V-type yellow subdwarf star Sol, the only star in the system. The system orbits a barycenter caused by the presence of Jupiter, a massive J-class planet.



The Sol system is essentially at the heart of known space.

Fauna & Flora

The Sol system hosts a widely varied and highly successful genesis group: the terragenids. While the group originated on Earth, a catastrophic planetary impact event in the geologically recent past caused a panspermic transfer of microscopic terragenid life to both Europa and Enceladus. Additionally, Saturn's moon Titan hosts an introduced biosphere of promethigenid organisms, transplanted from Prometheus by the Promethean colonists of the moon.
