| This article is about the planet Oannes. For species also known as Oannes, see Ohnes. |
Oannes, designated P3X-866 by the Tau'ri, is home to the Ohne species. It is one of three moons of a gas giant in the Milky Way Galaxy and sometime in the past was visited by the Ancients, whom left a Stargate behind.
Oannes has a large sea along with several small volcanic pockets, along the beach, which sprays out hot steam. (SG1: "Fire and Water")
Oannes' Stargate is located in a desert region, a piece from one of the moon's great salt sea. 30% of the surface is covered in between twelve and fifteen salt-water oceans of varying sizes, with the five largest housing the Ohne's underwater cities and complexes. (RPG: "Friends and Foes: Stargate Season Two")
The other 70% of the surface is covered in volcanoes of varying height and stability, with small geysers and gas pockets scattered between them. The thin atmosphere, high concentrations of gases, and volcanic activity make the surface of the world uninhabitable. (RPG: "Fantastic Frontiers: Stargate Season One")
