GJ 674 is a cool M-dwarf (about 0.35 solar masses, 3,600 K), 4.5 light-years from Earth. GJ 674 b is a 11.1-Earth-mass planet, with an orbital period of 4.7 days, at 0.039 AU from its star, on an eccentric orbit (e ≈ 0.20), discovered in 2007 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.
