The Procyon system is the home of the Andorian people, a founding member species of the United Federation of Planets.
The system is dominated by the gas giant Andor and its many moons, specifically the ice-moon Andoria. This world is famous for its glacial surface and vast subterranean cities sustained by geothermal heat.
A highly luminous and active binary star system. It produces significant, charged stellar winds that interact violently with the magnetospheres of the outer gas giants.
Subjected to inferno-level thermal radiation, this world possesses a crushing 1.24 G surface gravity and a highly corrosive carbon dioxide atmosphere.
A scorching terrestrial planet suffocating under an extreme carbon dioxide envelope with a surface gravity of 0.96 G.
Occupying a colder orbital band, this rocky world maintains a high-oxygen atmosphere but remains uninhabitable.
A freezing, high-nitrogen waste world representing the outer edge of the inner terrestrial planets.
A massive, highly turbulent, blue-hued ringed gas giant. It generates an immense gravitational well and powerful localized magnetic fields.
A perpetually frozen Class M moon. Its thriving subterranean biosphere and geothermally heated oceans are sustained entirely by the intense tidal friction generated by the gas giant Andor.
A smaller glacial moon characterized by highly active cryo-tectonic plates. Massive sheets of ice grind against one another, resulting in violent water geysers and vapor jets.
