Fictional info (?)
Suggested nameKyukyo
Planet typeCold planet
For this reason, scientists often classify Kyukyo and Shuku as "cold planets" to distinguish them from the other planets. This cold planet is named after the deity Kyukyo, the spirit of dreams.

Like Shuku, Kyukyo has been orbiting Kepler-90 within Nerepa Chinu's orbit as an inferior planet, and never moves more than 21 degrees away from Kepler-90.

An observer on Kyukyo would therefore see only one day every five years.

Surrounding Kyukyo is a large planetary ring system and a powerful magnetosphere.
