HD 222582 is a Sun-like G-type star (about 1.12 solar masses, 5,790 K, 1.13 solar radii), 42.2 light-years from Earth. HD 222582 b is a 8.37-Jupiter-mass companion, with an orbital period of 1.57 years, at 1.340 AU from its star, on an eccentric orbit (e ≈ 0.73), discovered in 1999 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.
