Kepler-186f is an exoplanet located about 500 light-years from Earth in the constellation of Cygnus. It orbits an M-dwarf star, Kepler-186, which is half the size and mass of our sun. Kepler-186f resides in the habitable zone, where conditions might allow liquid water to exist, making it a potential candidate for life. Its size and mass are similar to Earth's, leading to its classification as an Earth-like planet. Discovered in April 2014 by the Kepler telescope using the transit method, Kepler-186f has intrigued scientists due to its Earth-like characteristics and potential for habitability.
