ilmausma

Ilmausma is a fictional planet located in the Kepler-186 system. It is the fifth planet from its star, Kepler-186f, a red dwarf. Ilmausma is known for its unique atmospheric composition, which is rich in methane and nitrogen, giving its sky a perpetual twilight hue. The planet's surface is characterized by vast, frozen plains interspersed with liquid methane oceans and towering cryovolcanoes that periodically erupt, releasing plumes of frozen gases.

The climate on Ilmausma is extremely cold, with average temperatures well below freezing point of water. Life, if it exists, would likely be extremophilic, adapted to the harsh conditions and unique chemistry of the planet. Preliminary scans suggest the presence of complex organic molecules in the atmosphere and in the liquid methane oceans, hinting at the possibility of prebiotic chemistry or even simple life forms.

Ilmausma's orbit is stable, and it resides within the habitable zone of Kepler-186f, albeit at the outer edge. This means that while liquid water is unlikely on the surface, liquid methane can exist. The planet's magnetic field is weak, offering little protection from stellar radiation. Further exploration is planned to study its geological activity and potential for harboring life. The name "Ilmausma" is of fictional origin and was coined by the discoverers of the planet.
