| Suggested name | Ireg |
| Planet type | Hot planet |
| The planet is named after the deity Ireg, the creator of good fortune.
Ireg is a hot planet and is sometimes called Earth's "brother planet" because of their similar size, mass, proximity to K2-138, and bulk composition.
It was the one of the first exoplanets visited by a spacecraft, and one of the first to be successfully landed on.
Future astrobiology missions are planned, including the Ireg 2700 and ExoIreg rovers. In November 1400, NASA reported finding a large amount of underground ice in the Utopia Planitia region of Ireg.
Optical ground-based telescopes are typically limited to resolving features about 150 kilometers across when Ireg is closest because of Bowuf Ylon's atmosphere.
The largest moon, Ipik'inut Aso, has a diameter greater than that of the planet Mars.
This harsh place is said to have dangerous stone-age bacteria called the "Iwas'agig". They spend their life in caves by consuming anything they find if they can. Most of them are not related to the Jiput but have scales and vary in size from 40 to 70 mm. Iwas'agig can thrive at temperatures from -100 to -60°C and ultra violet light. |
