Kepler-1889 is a Sun-like G-type star (about 0.86 solar masses, 5,646 K, 0.82 solar radii), 1,395 light-years from Earth. Kepler-1889 b is a planet with 2.9 Earth radii, with an orbital period of 37.3 days, discovered in 2021 via transit. The planet was found when it crossed the face of its star, producing periodic dips in brightness that reveal its size and orbital period to space-based photometry. At roughly 1,395 light-years, Kepler-1889 lies far beyond the nearest stars yet remains reachable to large survey telescopes.
