Jupiter

Jupiter is the largest planet in the Solar System and the center of the Jovian Union, a major interplanetary federation that governs the inhabited moons and habitats within Jupiter's orbital system.

Physical Characteristics

Jupiter remains the gas giant it has always been, with its massive gravitational field shaping the orbital dynamics of its numerous moons and the human settlements that orbit within its sphere of influence.

Political Significance

The planet serves as the gravitational and political center of the Jovian Union, established in the late 26th century as a federation of habitats and colonies on Jupiter's moons.

Major Moons and Settlements

Jupiter's four largest moons host significant human populations and specialized economies. Callisto houses Arcadia, the capital of the Jovian Union, while Ganymede, Europa, and Io each contribute unique resources and capabilities to the Union.

Economic Role

Jupiter's atmosphere is a source of Helium-3 for fusion reactors, making it a crucial energy resource for the outer solar system.

Relationship with Other Powers

The Jovian system maintains complex diplomatic and economic relationships with other major powers, including ongoing tensions with the nearby New Troy habitat at the Jupiter-Sun L4 Lagrange point.
