Precise radial velocity data of the star from Xinglong Station and Okayama Astrophysical Observatory (OAO) revealed a Keplerian velocity variation with an orbital period of 1366.8 \\pm 5.7 days, a semiamplitude of 380.2 \\pm 3.2m s.1, and an eccentricity of 0.378 \\pm 0.008. Adopting a stellar mass of 2.7 \\pm 0.3 M\\odot, we obtain the minimum mass of the HD 175679 b is 37.3 \\pm 2.8 MJ, and the semimajor axis is 3.36 \\pm 0.12 AU.
