Persephone (Planet)

Persephone is the outermost planet orbiting Helios Alpha in the Cyrannus Star System. 
At only 1,100 km in diameter, Persephone is the smallest planet in the Four Systems (it is sometimes classified as a dwarf planet).
It has a thin, frigid atmosphere of nitrogen, methane and carbon monoxide.
Persephone's inclined and eccentric orbit suggests that it may be an escaped moon of Zeus.
