HD 129445 B
HD 129445 b is an eccentric Jupiter gas giant exoplanet orbiting the star HD 129445 which was discovered by the Magellan Planet Search Program in 2010. Its minimum mass is 1.6 times Jupiter's, and it takes 5 years to complete one orbit around HD 129445, a G-type star approximately 219 light years away. In 2023, the inclination and true mass of HD 129445 b were determined via astrometry.
