Kepler-1700 is a Sun-like F-type star (about 1.12 solar masses, 6,031 K, 1.09 solar radii), 718 light-years from Earth. Kepler-1700 b is a planet with 2.9 Earth radii, with an orbital period of 234 days, discovered in 2020 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 718 light-years, Kepler-1700 lies far beyond the nearest stars yet remains reachable to large survey telescopes.
