While the vast majority of multiple-planet systems have their orbital angularmomentum axes aligned with the spin axis of their host star, Kepler-56 is anexception: its two transiting planets are coplanar yet misaligned by at least40 degrees with respect to their host star. Additional follow-up observationsof Kepler-56 suggest the presence of a massive, non-transiting companion thatmay help explain this misalignment. We model the transit data along withKeck/HIRES and HARPS-N radial velocity data to update the masses of the twotransiting planets and infer the physical properties of the third,non-transiting planet. We employ a Markov Chain Monte Carlo sampler tocalculate the best-fitting orbital parameters and their uncertainties for eachplanet. We find the outer planet has a period of 1002 $\pm$ 5 days and minimummass of 5.61 $\pm$ 0.38 Jupiter masses. We also place a 95% upper limit of 0.80m/s/yr on long-term trends caused by additional, more distant companions.
