| Suggested name | Yuma Myoyu |
| Planet type | Huge cold gas giant |
| As seen from 2MASS J1118-0640, in a frame of reference that rotates with the orbital motion, it appears to rotate only once every two years.
The hydrogen chloride has probably photodissociated, and the free methane has been swept into interplanetary space by the solar wind because of the lack of a hydrogen deuteride (HD) layer.
Its north and south poles, therefore, lie where most other planets have their equators. |
| Atmosphere | Methane | 88% |
| Helium | 8.8% |
| Hydrogen chloride | 2.2% |
| Hydrogen deuteride (HD) | 0.13% |
| Ammonia | 0% |
| Molecular hydrogen | 0% |
| Water vapor | 0% |
| Atmospheric pressure | 13 bar |
