Jupiter (ETW)

Jupiter, or Mu Xing, is an artifical protostar orbiting Sol in the Solar System. Formerly a Gas Giant and the largest planet in the system, the planet was helioformed in the late 21st century to extend the system's habitable zone for terraforming the outer moons. The protostar has several satellities, four of which are terraformed, Io, Ganymede, Callisto and Europa. The star also has 64 other satellites, and irregular satellites in its orbit.
