| Suggested name | Xaje Riso Vi |
| Planet type | Hot planet |
| It has the densest atmosphere of the three hot planets, consisting of huge amounts of 2H2O. It may have had water vapor oceans in the past, but these would have vaporized as the temperature rose due to a runaway greenhouse effect.
Its north and south poles, therefore, lie where most other planets have their equators. |
| Atmosphere | 2H2O | 76% |
| Methane | 18% |
| Water vapor | 4.2% |
| Nitrogen | 1.4% |
| Neon | 0.14% |
| Atmospheric pressure | 7 bar |
