| Suggested name | Erun |
| Planet type | Cold planet |
| This planet is named after the deity Erun, the messenger of the sea.
The polar regions are constantly below 144°K (-129°C).
It is radically different from Gemitaw Epu in other respects.
In November 3500, NASA reported finding a large amount of underground ice in the Utopia Planitia region of Erun.
Erun is primarily composed of water vapor with a significant part of its mass being ethane, though ethane comprises only about a small amount of the number of molecules. |
| Atmosphere | Water vapor | 69% |
| Ethane | 15% |
| Molecular hydrogen | 13% |
| Ammonia | 2.2% |
| Atmospheric pressure | 0.09 bar |
