HD 206255 is a Sun-like G-type star (about 1.42 solar masses, 5,635 K), 75.2 light-years from Earth. HD 206255 b is a 0.11-Jupiter-mass companion, with an orbital period of 96.0 days, at 0.461 AU from its star, on an eccentric orbit (e ≈ 0.23), discovered in 2019 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.
