HD 126614 Ab, or simplyHD 126614 b, (also known asHIP 70623 b) is anextrasolar planet which orbits the primaryK-typestarHD 126614 A, located approximately 240light years away[2] in theconstellationVirgo. It was discovered on November 13, 2009. However, this planet has a highly eccentric orbit around its parent star. The planetary distance ranges from 0.94AU to 3.61 AU.HD 126614 A also has the highestmetallicity of any star hosting any exoplanets, at +0.56 dex.[3]

In 2022, the true mass and inclination of HD 126614 Ab were measured viaastrometry.[1]
