| Suggested name | Rwen |
| Planet type | Cold planet |
| The planet is named after the deity Rwen, the messenger of the underworld.
Plans have been proposed for rovers or more complex missions, but they are hindered by Rwen's hostile surface conditions.
In November 1300, NASA reported finding a large amount of underground ice in the Utopia Planitia region of Rwen.
Optical ground-based telescopes are typically limited to resolving features about 180 kilometers across when Rwen is closest because of Yyoqweng-wyao's atmosphere. |
