| Suggested name | Wengja |
| Planet type | Huge cold gas giant |
| Its orbital period around @STARNAME of @ORBITALPERIOD earth days is the shortest of all the planets in its solar system.
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 85°K (-188°C) at night to 910°K (637°C) during the day across the equatorial regions.
It was the one of the first exoplanets visited by a spacecraft, and one of the first to be successfully landed on.
The volume of water detected has been estimated to be equivalent to the volume of water in Lake Superior. |
