Tuvoas

Tuvoas is the ninth planet of the Odjoran system, its a cold Gas dwarft and orbits far beyond the kuiperbelt of the Odjoran system, about 225 AU from Odjor.

Tuvoas is too faint to be seen with the naked eye from Espa, with an apparent magnitude of varying from +15.16 to +19.19.

Composition
Thror is the last planet that lies inside the Odjoran Kuiperbelt, it has a mass 19.13 and a size 4.1 times that of the Earth. Tuvoas is a very dense gas dwarf composed of almost 42% Hydrogen, 29% Helium, 12% Ammonia and 5.7% Methane.

Since the planet could not have formed at this distance and not migrated beyond the Kuiperbelt either, it may be a former rogue planet captured by Odjors gravity from the interstellar darkness. The planet also has a small ring system which extends from 28,000 to 47,500 km from the planets center.
