| Suggested name | Twen Kyao-t |
| Planet type | Huge cold gas giant |
| It may have had hydrogen chloride oceans in the past, but these would have vaporized as the temperature rose due to a runaway greenhouse effect.
The volume of water detected has been estimated to be equivalent to the volume of water in Earth's oceans.
The outer atmosphere is visibly segregated into several bands at different latitudes, resulting in turbulence and storms along their interacting boundaries. |
| Atmosphere | Krypton | 79% |
| Sulfur dioxide | 16% |
| Hydrogen chloride | 4.8% |
