The planet was discovered as a result of examinations of data from the previously discovered exoplanet, Kepler-19b. Timing variations in the orbital period of the first planet necessitated gravitational forces to be acting upon the planet, resulting from an additional body in the vicinity, acting to cause a variation of transition of five minutes per orbit.[1][4] The lead author of the paper announcing the discovery was Sarah Ballard.[5]
