Éldonoros

Éldonoros is a fictional planet located in the Kepler-186 star system, approximately 500 light-years from Earth. It is the fifth and outermost known planet in its system, orbiting a red dwarf star. Éldonoros is a terrestrial planet, with a mass and radius suggesting it is a rocky world.

The planet's surface is characterized by vast, interconnected bodies of liquid, though the exact composition of this liquid is not fully understood. Extensive geological surveys indicate a surface rich in silicate minerals and a potential for a significant iron core. Atmospheric data suggests a thin but stable atmosphere, primarily composed of nitrogen and trace amounts of methane and carbon dioxide.

Éldonoros receives significantly less stellar radiation than Earth due to its distance from Kepler-186. This leads to a generally colder climate across the planet, with average surface temperatures well below freezing. However, internal geological activity and potential tidal heating from its star might create localized warmer regions.

Exploration of Éldonoros has been conducted remotely through advanced telescopic observations and probe missions. While no definitive signs of life have been detected, the presence of liquid and a stable atmosphere has prompted ongoing scientific interest in its potential habitability. Future missions are planned to gather more detailed information about its geology, atmosphere, and the composition of its liquid expanses.
