| Suggested name | Apigyo |
| Planet type | Small cold gas planet |
| When viewed from Myugata'rupyo, Apigyo 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 small cold gas planet is named after the deity Apigyo, the spirit of the sky.
When viewed from Myugata'rupyo, this proximity to Kepler-9 means the planet can only be seen near the western or eastern horizon during the early evening or early morning.
As seen from Kepler-9, in a frame of reference that rotates with the orbital motion, it appears to rotate only once every two years.
It may have had nitric oxide oceans in the past, but these would have vaporized as the temperature rose due to a runaway greenhouse effect.
A prominent result is the "great gray spot", a giant storm that is known to have existed for centuries since it was first detected by scanner. Surrounding Apigyo is a vast planetary ring system and a powerful magnetosphere. |
