| Suggested name | Chimya-zonyu |
| Planet type | Cold planet |
| 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 65°K (-208°C) at night to 1015°K (742°C) during the day across the equatorial regions.
It may have had helium oceans in the past, but these would have vaporized as the temperature rose due to a runaway greenhouse effect. The helium has probably photodissociated, and the free ethane has been swept into interplanetary space by the solar wind because of the lack of a planetary magnetic field. |
| Atmosphere | Ethane | 87% |
| Neon | 13% |
| Helium | 0.0058% |
| Methane | 0.00033% |
| Molecular hydrogen | 1.7E-5% |
| Atmospheric pressure | 8 bar |
