Esordia

Esordia is a fictional planet located in the fictional Kepler-186 system. It is the fifth and outermost known planet in the system, orbiting a red dwarf star. Esordia is approximately 1.5 times the size of Earth and is believed to have a rocky composition. Its orbit is considerably further from its star than Earth's is from the Sun, leading to significantly lower surface temperatures.

Due to its distance from Kepler-186, Esordia is thought to be a frigid world, likely covered in ice. The presence of a substantial atmosphere is a subject of ongoing scientific speculation, with models suggesting it could range from a thin, tenuous envelope to a thicker, more insulating layer. The color of the planet is generally depicted as a pale blue or white, reflecting the potential dominance of ice and atmospheric scattering.

The Kepler-186 system itself is notable for containing Kepler-186f, a planet that resides within the star's habitable zone. Esordia's position outside this zone makes it an unlikely candidate for liquid water on its surface, though subsurface oceans are not entirely ruled out given certain atmospheric and geological conditions. Research into Esordia continues through advanced telescopic observations and theoretical modeling, aiming to better understand its potential composition, atmospheric dynamics, and its place within the broader context of exoplanetary science.
