Jupiter is the fifth planet from Sol and the largest planet in the Sol system. It is a gas giant without a solid surface and its mass is greater than that of all the other planets in the Solar System combined. The planet is named after Jupiter, the king of the gods in ancient Roman religion.

Although the planet itself is uninhabitable, a number of its moons are inhabited by approximately forty-five million inhabitants in total. As a planetary system, it is de jure governed by both the United Nations and the Martian Congressional Republic.

Major Satellites

  • Ganymede, largest of Jupiter's moons, one of the largest system bodies without a substantial atmosphere, and whose domes are known as the "breadbasket of the Belt".
  • Callisto, second largest and tidally locked with Jupiter, is about half ice (mostly water and some volatiles) with a likely metal and rock core. It is a key strategic point in the Belt, since it has both MCRN and UNN shipyards.
  • Io, third largest moon, most geologically active object in the system with a high density, silicate rock crust, and an abundance of sulfur compounds. It hosts an inactive Helium-3 refinery.
  • Europa, fourth largest, primarily made of silicate rock, has a water-ice crust, and probably an iron–nickel core with a very thin atmosphere, composed primarily of oxygen.
