| Suggested name | Yerfer |
| Planet type | Huge warm gas giant |
| It is the second-brightest natural object in the night sky after Yisyao Wyin, reaching an apparent magnitude of -5 - bright enough to cast shadows at night and, sometimes, visible to the naked eye in broad daylight.
Yerfer's atmosphere is similar to Yisyao Wyin's in its primary composition of ethane and 2H2O, but it contains more "ices" such as water, ammonia, and methane, along with traces of other hydrocarbons. This huge warm gas giant is named after the deity Yerfer, the god of war.
Yerfer is primarily composed of ethane with a significant part of its mass being 2H2O, though 2H2O comprises only about a limited amount of the number of molecules. |
| Atmosphere | Ethane | 50% |
| 2H2O | 37% |
| Helium | 12% |
| Oxygen | 0.019% |
| Hydrogen deuteride (HD) | 0.0082% |
| Carbonyl sulfide | 0.0018% |
| Sulfur dioxide | 0% |
| Ammonia | 0% |
| Atmospheric pressure | 0.4 bar |
