Trinia

Basic Information:
The first planet from Alpha. The planet appears to be covered in an ocean of tritium, kept (somewhat) stable by Alpha's radiation, and kept from vaporizing from the extreme pressure of its helium "atmosphere". The "crust" of this planet appears to be made out of about 40% uranium, 30% lead, 20% cadmium, and 10% plutonium.
Important Information:
Numerous scans have been done over the years, and it seems as if the planet is slowly becoming less stable, increasing in temperature and radioactivity. It is very likely that Trinia will completely blow up, irradiating its moons and some of the Alpha System. In fact, several of Alpha's asteroids are theorized to be the result of explosions on Trinia, resulting in pieces of its crust being launched into Alpha orbit.
Lore:
Trinia was formed about 6,000 Earth-years ago, after its parent star Alpha was created. Trinia was discovered early on by the Ferragor, who attempted to set up a mine to extract plutonium from the surface, but the attempt ended in catastrophic failure. Since then, people have avoided the planet, fearing that they may meet the same fate that the Ferrgoran would-be colonists met. Trinia may seem insignificant, but it actually helped to shape several of the events in the history of the Alpha system.
