Kepler-440b (also known by its Kepler Object of Interest designation KOI-4087.01) is a confirmed super-Earth exoplanet orbiting within the habitable zoneofKepler-440, about 850 light-years (261 pc) from Earth.[1] 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 confirmation of the exoplanet on 6 January 2015.[4]
