HD 72659 b is a superjovian exoplanet massing at least 3.3 MJ orbiting at 4.77 AU from the star, taking 3630 days to complete one orbit. The orbital distance range from 3.49 AU to 6.05 AU with orbital eccentricity of 0.269. In 2022, the inclination and true mass of HD 72659 b were measured via astrometry.
