| Suggested name | Kyahyo Shi |
| Planet type | Cold planet |
| The planet telescopically displays the complete range of phases, similar to Venus and the Moon, as it moves in its inner orbit relative to PSR J1836-2354A, which reoccurs over the so-called synodic period approximately every 203 days.
It may have had methane oceans in the past, but these would have vaporized as the temperature rose due to a runaway greenhouse effect. The methane has probably photodissociated, and the free ozone has been swept into interplanetary space by the solar wind because of the lack of a planetary magnetic field. |
| Atmosphere | Ozone | 53% |
| Hydrogen deuteride (HD) | 39% |
