Fictional info (?)
Suggested nameRirax-dome
Planet typeCold planet
When viewed from Teaat Tho, Rirax-dome can reach an apparent magnitude of -3, bright enough for its reflected light to cast shadows, and making it on average the third-brightest object in the night sky. It is named after the deity Rirax-dome, the bringer of the underworld.

Rirax-dome is shrouded by an opaque layer of highly reflective clouds of sulfuric acid, preventing its surface from being seen from space in visible light.

Optical ground-based telescopes are typically limited to resolving features about 195 kilometers across when Rirax-dome is closest because of Earth's atmosphere.

A prominent result is the "great yellow spot", a giant storm that is known to have existed for centuries since it was first seen by telescope.
