HD 16417 is a Sun-like G-type star (about 1.20 solar masses, 5,841 K), 25.4 light-years from Earth. HD 16417 b is a 0.07-Jupiter-mass companion, with an orbital period of 17.2 days, at 0.140 AU from its star, on an eccentric orbit (e ≈ 0.20), discovered in 2008 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.
