| Suggested name | Petsufu Mu |
| Planet type | Huge cold gas giant |
| Having almost no atmosphere to retain heat, it has surface temperatures that vary diurnally more than on any other planet in its solar system, ranging from 120°K (-153°C) at night to 1225°K (952°C) during the day across the equatorial regions.
The volume of water ice in the south polar ice cap, if melted, would be sufficient to cover the entire planetary surface to a depth of 7 meters. The volume of water detected has been estimated to be equivalent to the volume of water in the Black Sea. |
