Pylan

Pylan is a fictional planet located in the fictional Kepler-186 star system, a real star system located approximately 580 light-years away from Earth. Pylan is described as a terrestrial planet, meaning it is rocky and has a solid surface, similar to Earth. It is situated within the habitable zone of its star, Kepler-186f, which is a red dwarf. This means that Pylan orbits its star at a distance where liquid water could potentially exist on its surface, a key ingredient for life as we know it.

The planet's size is estimated to be about 1.1 times the radius of Earth. Its atmosphere is not fully described but is suggested to be capable of supporting plant life, hence the name "Pylan," which hints at a connection to plant life. While Pylan is a fictional construct, its description is based on scientific understanding of exoplanets and the conditions necessary for habitability. The Kepler-186 system, and specifically the exoplanet Kepler-186f, are real astronomical discoveries, and Pylan is a creative interpretation or embellishment of such discoveries, often used in speculative fiction or educational contexts to illustrate the possibilities of worlds beyond our solar system. The characteristics attributed to Pylan are intended to make it a plausible candidate for harboring life, sparking imagination about extraterrestrial environments.
