Kepler-955 is a Sun-like G-type star (about 0.89 solar masses, 5,350 K, 0.84 solar radii), 550 light-years from Earth. Kepler-955 b is a planet with 3.1 Earth radii, with an orbital period of 14.5 days, discovered in 2016 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 550 light-years, Kepler-955 lies far beyond the nearest stars yet remains reachable to large survey telescopes.
