Ségdán

Ségdán is a fictional planet located in the Kepler-186 system. It is the fifth and outermost planet discovered orbiting the star Kepler-186. Ségdán is a terrestrial planet, meaning it is rocky and has a solid surface, similar to Earth. Its orbital period is approximately 130 Earth days, placing it within the habitable zone of its star, though the extent of its habitability remains a subject of ongoing scientific speculation and fictional exploration.

The planet's surface is characterized by a diverse geological landscape, with evidence suggesting the presence of both vast oceans and significant continental landmasses. Atmospheric studies indicate a composition that includes nitrogen and oxygen, with trace amounts of other gases. The temperature range on Ségdán is believed to be within a spectrum that could potentially support liquid water, a key ingredient for life as we know it.

Ségdán's star, Kepler-186, is a red dwarf star, which means it is cooler and dimmer than our Sun. This influences the amount of light and heat Ségdán receives. Due to the dimmer nature of its star, Ségdán orbits closer to Kepler-186 than Earth orbits the Sun, yet it still resides within the star's habitable zone. The planet's axial tilt is thought to be minimal, suggesting that seasonal variations might be less pronounced compared to Earth. Research and fictional narratives often explore the potential for unique flora and fauna adapted to the specific conditions of Ségdán.
