Suggested nameJaeojura
Planet typeSmall hot gas planet
It is a small hot gas planet planet with a mass one-thousandth that of K2-199, but two-and-a-half times that of all the other planets in its solar system combined. This small hot gas planet is named after the deity Jaeojura, the spirit of war.

Jaeojura's surface appears partially scarred and is similar in appearance to the Moon's, indicating that it has been geologically inactive for billions of years.

It may have had methane oceans in the past, but these would have vaporized as the temperature rose due to a runaway greenhouse effect.

Jaeojura is primarily composed of carbon dioxide with a significant part of its mass being water, though water comprises only about a limited fraction of the number of molecules.
