| Suggested name | Zhyun |
| Planet type | Hot planet |
| Zhyun is the strangest and innermost planet in its solar system.
This hot planet is named after the deity Zhyun, the goddess of destruction.
The methane has probably photodissociated, and the free molecular hydrogen has been swept into interplanetary space by the solar wind because of the lack of a planetary magnetic field.
The volume of water detected has been estimated to be equivalent to the volume of water in Earth's oceans. |
| Atmosphere | Molecular hydrogen | 41% |
| Nitrogen | 33% |
| Methane | 14% |
| Xenon | 8.9% |
| Hydrogen chloride | 3.2% |
| Hydrogen deuteride (HD) | 0.2% |
| Krypton | 0.00023% |
| Hydrogen peroxide | 0.00014% |
| Atmospheric pressure | 1.7 bar |
