HD 11506 b is anextrasolar planet that orbits thestarHD 11506 167light years away in theconstellation ofCetus. This planet was discovered in 2007 by theN2K Consortium using theKeck telescope to detect theradial velocity variation of the star caused by the planet.[2] A second planet,HD 11506 c, was discovered in 2015.[3]
In 2022, the true mass and inclination of HD 11506 b were measured viaastrometry, along with the discovery of a third planet in the system.[1]
