Abstract: We present a new study of a recently discovered exoplanetary system WASP-118. The system consists of an F-type star and a close-in giant planet (an inflated hot Jupiter). Using Kepler-K2 observations, we re-determined the orbital and physical parameters of the system. Our results are in good agreement with the values published in the literature. The precise times of all transits were determined, however, no significant transit timing variations were detected. Our analysis of an upper mass limit allows us to include additional Earth-mass planet(s) near to mean-motion resonance(s).
