Doppler velocities for HD 160691. The rms to the best‐fit Keplerian (solid line) is 3 m s⁻¹. The period is 743.5 days, and the semiamplitude is 53.6 m s⁻¹. Assuming the mass of HD 160691 is 1.08 ﹩M_{\odot }﹩, the minimum (﹩M\mathrm{sin}\,i﹩) mass of the companion is 1.97 ﹩M_{\mathrm{J}\,}﹩, and the semimajor axis is 1.65 AU. The orbital eccentricity is 0.62, similar to other planets orbiting beyond 1 AU.
