HD 30669 is a Sun-like G-type star (about 0.92 solar masses, 5,400 K, 0.91 solar radii), 58.1 light-years from Earth. HD 30669 b is a 0.47-Jupiter-mass companion, with an orbital period of 4.61 years, at 2.690 AU from its star, on an eccentric orbit (e ≈ 0.18), discovered in 2014 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.
