| Suggested name | Rionhe |
| Planet type | Terrestrial |
| The smooth Borealis basin in the northern hemisphere covers 27 percent of the planet and may be a giant impact feature.
The two polar ice caps appear to be made largely of water.
Because of its fast rotation, the planet's shape is that of an oblate spheroid (it has a slight but noticeable bulge around the equator). |
