Thadus 0002 4 is the fourth planet from the binary pair at the center of the Thadus 0002 System, 2.28 light-years from the Nivenia System. Thadus 0002 4 is a very massive gas giant, denser than most rocky planets due to both its extremely high mass and extremely high water content. While it only contains 7% of its mass in carbon, even that is such a huge amount that it would outweigh smaller gas giant. This would make Thadus 0002 4 a good planet for colonization by the Nivenian Empire, but it has such a deep gravity well that it would literally take a century of output from the Dyson Sphere in the Caeruleo System to rip the planet apart.
