HD 30177 b is an extrasolar planet located approximately 178 light-years away in the constellation of Dorado orbiting the star HD 30177. This is one of the most massive planets ever detected by the radial velocity method. In addition the planet orbits far from the star about 4 AU away taking 2770 days (7.58 years) to orbit the star. Even though the massive planet is orbiting at 4 AU from the star the radial velocity semi-amplitude is high around 146.8±2.8 m/s.
