The Solar System, also referred to as the First System by later interstellar colonists, is the home planetary system of Earth, a terrestrial life-bearing planet, and the homeworld of Earth lifeforms, including humans.

History Edit

Humanity developed technology sufficient for spaceflight in the mid 20th century.

During the course of the 21st century, a gradual manned colonisation effort followed, establishing colonies on the Moon, later Mars and some of the moons of Jupiter (e.g. Europa).
