Kepler-296f

Kepler-296f^[1][2][3] (also known by its Kepler Object of Interest designation KOI-1422.04) is a confirmed super-Earth exoplanet orbiting within the habitable zone of Kepler-296. The planet was discovered by NASA's Kepler spacecraft using the transit method, in which the dimming effect that a planet causes as it crosses in front of its star is measured. NASA announced the discovery of the exoplanet on 26 February 2014.^[1]
