| Suggested name | Lephaë Pa |
| Planet type | Hot planet |
| The atmospheric pressure at the planet's surface is 0.013 bar, or roughly the pressure found 1305 m under the oceans of Earth.
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 14 meters. The volume of water detected has been estimated to be equivalent to the volume of water in the Black Sea. |
