HD 30177 b

Extrasolar planet in the constellation Dorado

HD 30177 b is an extrasolar planet located approximately 181.6 light-years away in the constellation of Dorado, orbiting the star HD 30177.

Discovery

This planet was discovered on June 13, 2002^[1] by Tinney, Butler, and Marcy et al. using the Doppler spectroscopy from the Anglo-Australian Telescope.^[3]^[4]

Properties

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. In 2022, the inclination and true mass of HD 30177 b were measured via astrometry, showing the true mass to be close to the minimum mass.^[2]
