HD 23127 b is a jovian extrasolar planet orbiting the star HD 23127 at the distance of 2.29 AU, taking 3.32 years to orbit. The orbit is very eccentric, a so-called "eccentric Jupiter". At periastron, the distance is 1.28 AU, putting in its outer edge of the habitable zone, and at apastron, the distance is 3.30 AU. The mass is at least 1.37 times Jupiter. Only the minimum mass is known because the inclination is not known.
