Kepler-432b (also known by its Kepler Object of Interest designation KOI-1299.01) is a hot super-Jupiter (or "warm" super-Jupiter) exoplanet orbiting the giant star Kepler-432 A, the innermost of two such planets discovered by NASA's Kepler spacecraft. It is located about 2,830 light-years (870 parsecs, or nearly 2.684×1016 km) from Earth in the constellation Cygnus. 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.
