Pölyön

Pölyön is a fictional planet located in the Kepler-186 system. It is the fifth and outermost known planet orbiting the red dwarf star Kepler-186, approximately 500 light-years from Earth. Pölyön is roughly the size of Earth, with a diameter about 1.1 times that of our planet. Its orbital period is approximately 130 Earth days.

The planet's surface conditions are not fully understood. Given its distance from the star, Pölyön is believed to be a cold world, potentially with a significant ice cover. However, it resides within the habitable zone of Kepler-186, meaning it could theoretically support liquid water on its surface if atmospheric conditions were favorable. The composition of its atmosphere is unknown, which plays a crucial role in determining its surface temperature and habitability.

Pölyön's discovery was part of the Kepler Space Telescope's mission to find exoplanets, particularly those similar in size to Earth. Its existence highlights the potential for Earth-like planets to orbit red dwarf stars, which are the most common type of star in the Milky Way galaxy. Further observations and future telescope missions may provide more detailed information about Pölyön's characteristics, including its potential for hosting life.
