Kepler-1229b[1] (also known by its Kepler Object of Interest designation KOI-2418.01) is a confirmed super-Earth exoplanet, likely rocky, orbiting within the habitable zone of the red dwarf Kepler-1229, located about 870 light years (267 parsecs) from Earth in the constellation of Cygnus.[4][2] It was discovered in 2016 by the Kepler space telescope.[5] The exoplanet was found by using the transit method, in which the dimming effect that a planet causes as it crosses in front of its star is measured.
