TYC 4282-00605-1 is an orange K-type dwarf (about 0.97 solar masses, 4,300 K, 16.2 solar radii), 464 light-years from Earth. TYC 4282-00605-1 b is a 10.8-Jupiter-mass companion, with an orbital period of 102 days, at 0.422 AU from its star, on an eccentric orbit (e ≈ 0.28), discovered in 2017 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.
