The brightness of Kepler-429 changes unpredictably by up to 0.13 magnitudes. It has been classified as a V361 Hydrae variable, but also as a V1093 Herculis variable, which typically has slower variations and a cooler temperature. Over 100 pulsation modes were identified with periods from 256 seconds to over three hours.
