The Solar System is the collection of planets, moons and asteroids bound to the Sol star due to gravity and the space surrounding them.


Before the 21st century, humankind only lived on Earth and explored space on missions. In the 21st century, however, humankind traveled to several other planets and moons to colonize them.[1] Hyperspace technology allowed travel in days, both people and package delivery.[2][3][4]

As mankind traveled back and forth in the solar system, trash was discarded and collected in various areas.[5]

Planets and major locations


Mercury is the innermost and smallest planet in the Solar System.

A space station near Ganymede advertised imports from Mercury.[5]


Main article: Venus

Venus is close in size to Earth, and is structurally similar to Earth. It was colonized and given a habitable atmosphere.[2]


Main article: Earth

Earth is the largest and densest of the four inner planets, the only one known to have current geological activity, and is the only place in the solar system where life naturally existed. After the Astral Gate accident near its moon, Luna, however, the surface was much less habitable.[1]


Main article: Mars

Mars is smaller than Earth and Venus. It is a terrestrial planet with a thin atmosphere, having surface features reminiscent both of the impact craters of the Moon and the volcanoes, valleys, deserts and polar ice caps of Earth. It was in these craters that colonies were created.[6]

Bohemian Junkheap

Main article: Bohemian Junkheap

The Bohemian Junkheap was an ungoverned location in space that consisted of discarded ship parts and other materials. A colony of people live there.[3]

Asteroid belt

Main article: Asteroid belt

The asteroid belt was made of asteroids between Mars and Jupiter. Several asteroids were mined, such as the Linus Mine, and some were inhabited, like Tijuana.[6][7]


Main article: Jupiter

Jupiter is the fifth planet from the Sun and the largest planet within the Solar System. The four largest moons, Ganymede, Callisto, Io, and Europa, were colonized and there were space stations.


Saturn is the sixth planet from the Sun and the second largest planet in the Solar System, after Jupiter. One of its moons, Titan, was habitable, if barely.[8]


Uranus was the next planet after Saturn. There was an observatory called the Fourth Observatory of Uranus.[4]


Neptune was the next planet after Uranus.


Main article: Pluto

Pluto was the last major orbiting body in the Solar System. It had a prison colony in 2071.[9]


Mercury was only shown on a sign on the restaurant space station in Gateway Shuffle.

Neptune was not mentioned in the series or movie.
