Kepler-186f is an exoplanet orbiting the red dwarf Kepler-186, about 550 light-years from the Earth. It is the first planet with a radius similar to Earth's to be discovered in the habitable zone of another star. NASA's Kepler spacecraft detected it using the transit method, along with four additional planets orbiting much closer to the star.
