HD 224693 is a Sun-like G-type star (about 1.31 solar masses, 5,894 K, 1.93 solar radii), 93.5 light-years from Earth. HD 224693 b is a 0.70-Jupiter-mass companion, with an orbital period of 26.7 days, at 0.191 AU from its star, on an eccentric orbit (e ≈ 0.10), 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.
