GJ 4274 is a cool M-dwarf (about 0.18 solar masses, 3,228 K, 0.19 solar radii), 7.2 light-years from Earth. GJ 4274 b is a 3.0-Earth-mass planet, with an orbital period of 1.6 days, at 0.015 AU from its star, discovered in 2026 via radial velocity. GJ 4274 c is a 8.4-Earth-mass planet, with an orbital period of 69.6 days, at 0.186 AU from its star, discovered in 2026 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.
