BD+15 2375 is an orange K-type dwarf (about 1.08 solar masses, 4,649 K, 8.95 solar radii), 768 light-years from Earth. BD+15 2375 b is a 1.06-Jupiter-mass companion, with an orbital period of 153 days, at 0.576 AU from its star, discovered in 2016 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. BD+15 2375 b circles its star within the inner habitable zone.
