HD 147379 is a cool M-dwarf (about 0.58 solar masses, 4,090 K), 10.8 light-years from Earth. HD 147379 b is a 0.07-Jupiter-mass companion, with an orbital period of 86.6 days, on an eccentric orbit (e ≈ 0.06), 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. Its low mass makes HD 147379 b a Neptune- or super-Earth-class world rather than a gas giant.
