HD 23127 is a Sun-like G-type star (about 1.21 solar masses, 5,843 K, 1.49 solar radii), 93.9 light-years from Earth. HD 23127 b is a 1.53-Jupiter-mass companion, with an orbital period of 3.32 years, at 2.370 AU from its star, on an eccentric orbit (e ≈ 0.41), discovered in 2006 via radial velocity. The planet betrayed itself through the star's reflex motion — a technique that first revealed worlds around Sun-like stars in the 1990s and remains a workhorse of exoplanet discovery. The planet's marked eccentricity suggests past scattering events or perturbations from unseen companions.
