| Suggested name | Apigyo |
| Planet type | Small cold gas planet |
| 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. |
