HD 11506 b is an extrasolar planet that orbits the star HD 11506 169 light years away in the constellation of Cetus. This planet was discovered in 2007 by the N2K Consortium using the Keck telescope to detect the radial velocity variation of the star caused by the planet.[3] A second planet, HD 11506 c, was discovered in 2015.[2]
