Solar System

The Solar System is a star system that contains 10 planets. It is the birthplace of humanity and for several millennia, was the only star system in the universe known to humans to contain life. As of 3252 AD, around 320 billion humans and around 190 million aliens from 40 different species live across its 4 habitable planets, 3 habitable dwarf planets and 11 habitable moons.

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 are obviously not terraformed, but their moons (e.g. Europa) have been terraformed by humans.
