Hasta abril de 2014, Kepler-186f es el planeta más pequeño encontrado dentro de la zona habitable de una estrella y se cree que pueda albergar agua en forma líquida. Se encuentra a unos 492,3 años luz de nuestro planeta y su radio es tan sólo un 11% más grande que el del planeta azul.
Kepler-186 f is a super Earth exoplanet that orbits an M-type star. Its mass is 1.71 Earths, it takes 129.9 days to complete one orbit of its star, and is 0.432 AU from its star. Its discovery was announced in 2014.
17 de abr. de 2014 · Kepler-186f resides in the Kepler-186 system about 500 light-years from Earth in the constellation Cygnus. The system is also home to four inner planets, seen lined up in orbit around a host star that is half the size and mass of the sun.
Kepler-186f is the first Earth-size planet discovered in the potentially 'habitable zone' around another star, where liquid water could exist on the planet's surface. Its star is much cooler and redder than our Sun.
Kepler-186f (also known by its Kepler object of interest designation KOI-571.05) is an Earth-sized exoplanet orbiting within the habitable zone of the red dwarf star Kepler-186, the outermost of five such planets discovered around the star by NASA's Kepler spacecraft.
17 de abr. de 2014 · The discovery of Kepler-186f confirms that planets the size of Earth exist in the habitable zone of stars other than our sun. While planets have previously been found in the habitable zone, they are all at least 40 percent larger in size than Earth, and understanding their makeup is challenging.
