Fictional info (?)
Suggested nameYongp
Planet typeTerrestrial
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 95°K (-178°C) at night to 1190°K (917°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.

Planet is inhabitated by strange but ultra advanced plants that spend their life by finding nourishment in the Ying'qweng. Most Twayyo'x are not related to the Waifyunq and have 8 tentacles and vary in length from 1 to 2 mm. They can endure temperatures from -70 to -50°C and even extreme gravity.
Estimated population26000000000
AtmosphereH2O99%
Atmospheric pressure0.005 bar
