Rivon

Rivon is a moon orbiting an ice giant in the Centauri system. It's an intermediate size between Titan & Ganymede.

Habitability
Rivon is covered in water, which was unfrozen after several trillion tons of CO2 were sent into the atmosphere after it experienced incredible tidal stresses when it was captured by its host planet, 1 billion years ago. 18 million years after the oceans became liquid, life began to develop, resulting in a bacteria much like blue green algae to evolve after 50 million years. this bacteria slowly turned its atmosphere of CO2 and Neon into an atmosphere of 47% Neon, 32% Oxygen & 20% Nitrogen.
