Fictional info (?)
Suggested nameHyunyu Mi
Planet typeCold planet
When viewed from Nehyu'ki, Hyunyu Mi 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. This cold planet is named after the deity Hyunyu Mi, the bringer of fear.

Hyunyu Mi's surface appears extremely scarred and is similar in appearance to the Moon's, indicating that it has been geologically inactive for billions of years.

The smooth Borealis basin in the northern hemisphere covers 20 percent of the planet and may be a giant impact feature.

The two polar ice caps appear to be made largely of rock.

Hyunyu Mi is primarily composed of oxygen with a significant part of its mass being water vapor, though water vapor comprises only about a small amount of the number of molecules.
