Kepler 186 f planet
Kepler-186f orbits its star at a distance of about 0.43 AU (64,000,000 km; 40,000,000 mi) from its host star with an orbital period of roughly 130 days, and a mass and radius around 1.44 and 1.17 times that of Earth, respectively. As one of the more promising candidates for habitability, it was the first planet with a radius similar to Earth's to be discovered in the habitable zone of another star. However, key components still need to be found to determine its habitability for life, including an atmosphere and its composition and if liquid water can exist on its surface.Kepler 186f planet
Analysis of three years of data was required to find its signal.[8] NASA’s Kepler space telescope detected it using the transit method (in which the dimming effect that a planet causes as it crosses in front of its star is measured), along with four additional planets orbiting much closer to the star (all modestly larger than Earth).[5] The results were presented initially at a conference on 19 March 2014[9] and some details were reported in the media at the time.[10] The planet was announced on 17 April 2014,[3] simultaneously with publication of a scientific paper in Science.
