HD 89307 is a Sun-like G-type star (about 1.27 solar masses, 5,955 K, 1.10 solar radii), 32.0 light-years from Earth. HD 89307 b is a 2.11-Jupiter-mass companion, with an orbital period of 5.93 years, at 3.270 AU from its star, on an eccentric orbit (e ≈ 0.20), discovered in 2009 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.
