Serenis

Serenis is a fictional planet located in the Kepler-186 star system. It is the fifth and outermost known planet orbiting the red dwarf star Kepler-186, situated within its habitable zone. This positioning suggests that Serenis could potentially harbor liquid water on its surface, a key ingredient for life as we know it. The planet is believed to be roughly Earth-sized, although its exact mass and composition are not precisely known.

The Kepler-186 system is located approximately 500 light-years away from Earth in the constellation Cygnus. Kepler-186f, as Serenis is also designated, is one of five planets discovered orbiting Kepler-186. Its orbital period is estimated to be around 130 Earth days. Due to the dimmer nature of its host star, a red dwarf, Serenis likely receives less stellar radiation than Earth. This means that for liquid water to exist, Serenis would need a sufficient atmosphere to trap heat.

Scientists are interested in Serenis as a prime candidate for further study in the search for exoplanets that might support life. While direct observation of Serenis's atmosphere or surface features is not yet possible with current technology, its discovery marks a significant step in understanding the prevalence of potentially habitable worlds beyond our solar system. Future telescopic missions may provide more detailed information about this intriguing exoplanet.
