| Suggested name | Etafos-use |
| Planet type | Terrestrial |
| The sulfur dioxide has probably photodissociated, and the free xenon has been swept into interplanetary space by the solar wind because of the lack of a methane layer. |
| Atmosphere | Xenon | 76% |
| Water vapor | 18% |
| Sulfur dioxide | 4.4% |
| Methane | 0.52% |
| Carbonyl sulfide | 1.0E-5% |
| Atmospheric pressure | 0.05 bar |
