HD 175541 is an orange K-type dwarf (about 1.39 solar masses, 5,013 K, 4.19 solar radii), 130 light-years from Earth. HD 175541 b is a 0.60-Jupiter-mass companion, with an orbital period of 298 days, at 0.975 AU from its star, on an eccentric orbit (e ≈ 0.11), 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.
