==Discovery== Kepler-78b is the only planet to be found orbiting the star KIC 8435766, now known as Kepler-78. The planet was discovered in 2013 by analyzing data from the Kepler space telescope. The planet was detected as it passed across the surface of its host star, as viewed from Earth. It was also found by the effects of occultation as it passed behind the star. Reflected light from the parent star due to orbital phases was also detected. It was not at first designated as a Kepler object of interest, as data analysis failed to identify it due to its short orbital period.
