Yrirlitums

Yrirlitums is a fictional planet located in the Kepler-186 system. It is the fifth planet from its star, Kepler-186f, a red dwarf. Yrirlitums is known for its unusual atmospheric composition, primarily consisting of argon and methane, which gives its sky a distinctive orange hue. The planet's surface is characterized by vast, shallow oceans of liquid ethane and large, crystalline methane formations that reach impressive heights.

The surface temperature on Yrirlitums is extremely low, averaging around -170 degrees Celsius. Despite these harsh conditions, scientists speculate about the possibility of extremophile life forms that might exist in the planet's subsurface oceans, potentially fueled by geothermal activity. These hypothetical organisms would need to be adapted to extreme cold and the specific chemical environment of Yrirlitums.

Yrirlitums has a thin atmosphere and experiences very little light due to its distant and dim star. This results in prolonged periods of twilight and limited visibility. Its gravitational pull is approximately 0.8 times that of Earth. Due to its composition and distance from its star, Yrirlitums is considered an unlikely candidate for human colonization without significant technological intervention. Research continues into its geological processes and the potential for life.
