Fictional info (?)
Suggested nameMarpho
Planet typeCold planet
Marpho's atmosphere is similar to Nomia Eury's in its primary composition of ethane and carbon monoxide, but it contains more "ices" such as water, ammonia, and methane, along with traces of other hydrocarbons. This planet is named after the deity Marpho, the creator of the underworld.

The atmospheric pressure at the planet's surface is 60 bar, or roughly the pressure found 1440 m under the oceans of Nomia Eury.

There are ongoing investigations assessing the present habitability potential of Marpho, as well as the possibility of extant life.
