Sol I — Mercury
UNH- TypeRocky
Tidally locked, with extreme surface temperatures. Automated mining operations extract rare metals. No permanent human habitation.
Sol
Overview
Humanity's origin system and the political, economic and cultural centre of human civilisation. Earth is home to roughly 150 million families, the wealthiest population in human history, while Mars hosts the largest urban concentration outside Earth. UN authority here is absolute and no private military operations are permitted; the Dyson Swarm provides effectively unlimited energy.

Sol II — Venus
UNH- TypeRocky (greenhouse)
Crushing atmosphere, surface temperature exceeding 450°C. Only high-altitude research stations exist; surface operations require Salus armour at minimum.
Art pending
Sol III — Earth
HPWHomeworld, recovered from the Collapse over centuries. Roughly 150 million families occupy private estates averaging a square kilometre each, the entire habitable surface divided among the wealthiest population in human history. Cities exist only as administrative centres.

Luna
UMW- TypeRocky (airless)
- SettlementLacus Somniorum
Earth's moon, extensively developed since the First Exodus. Over three billion live in arcologies and subsurface warrens, running the heavy industry and services Earth's estate owners prefer not to see.
Art pending
Sol IV — Mars
UMW- TypeCold terrestrial
- SettlementOlympus Mons Arcology
Fully terraformed over eight centuries, now breathable with open water. A population exceeding fifteen billion is concentrated in arcologies and industrial zones. Olympus Mons Arcology is the largest single structure in human space.

Asteroid Belt
DZ- TypeDebris field
- SettlementCeres Station
Extensive mining operations. Ceres hosts the Belt's largest settlement, with thousands of smaller habitats scattered throughout.
Art pending
Sol V — Jupiter
UNH- TypeGas giant
Massive gas giant. Ganymede houses over a billion in domed cities, and Europa's population approaches 500 million around its subsurface ocean. Atmospheric volatile harvesting feeds Sol's energy and chemical industries.
Art pending
Sol VI — Saturn
UNH- TypeGas giant
- SettlementTitan Dome
Gas giant with an extensive ring system. Titan hosts over 500 million in domed settlements, the largest population in the outer system. Volatile harvesting from atmosphere and rings supplies fuel and chemicals across Sol.
Art pending
Sol VII — Uranus
UNH- TypeIce giant
Distant ice giant. Minimal development, automated fuel harvesting.
Art pending
Sol VIII — Neptune
UNH- TypeIce giant
Outermost major planet. Automated operations only.
Art pending
Kuiper Belt
DZ- TypeDebris field
Outer system debris. Scattered outposts at the edge of the system.
