| Suggested name | Shoha |
| Planet type | Small hot gas planet |
| It has the longest rotation period (445 days) of any planet in its solar system and rotates in the opposite direction to most other planets.
It is the coldest planetary atmosphere in its solar system, with a minimum temperature of 65°K (-208°C), and has a complex, layered cloud structure with nitrogen thought to make up the lowest clouds, and molecular hydrogen the uppermost layer of clouds.
Having almost no atmosphere to retain heat, it has surface temperatures that vary diurnally more than on any other planet in its solar system, ranging from 75°K (-198°C) at night to 490°K (217°C) during the day across the equatorial regions.
The carbonyl sulfide 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. |
| Atmosphere | Molecular hydrogen | 99% |
| Nitrogen | 0.47% |
| Carbonyl sulfide | 0.16% |
| Atmospheric pressure | 18 bar |
