The Solar System.
The Solar System is a star system which contains 10 planets. It is the birthplace of humanity, and for several millennia, was the only star system in the Milky Way known to humans to contain life, until about 2030.
As of 3300 AD, around 160 billion humans and 140 million aliens from nearly 40 different species live across its 4 habitable planets, 3 habitable dwarf planets, and 11 habitable moons.
System[]
The Solar System contains about 10 planets. 4 of these planets have been terraformed, and 3 dwarf planets were also terraformed. Some planets like Jupiter have obviously not been terraformed, but their moons (e.g. Titan) have been.
Legend:
- Red = Uninhabitable
- Purple = Uninhabitable, but has habitable moons
- Lavender = Uninhabitable, but has habitable moons (via Terraformation)
- Orange = Habitable, but uninhabitable to any Earth-like life
- Yellow = Habitable (via Terraformation)
- Green = Habitable
