Kepler-1705 is a Sun-like F-type star (about 1.14 solar masses, 6,312 K, 1.26 solar radii), 1,633 light-years from Earth. Kepler-1705 b is a 4.5-Earth-mass planet, with an orbital period of 9.0 days, discovered in 2021 via transit. Kepler-1705 c is a 5.4-Earth-mass planet, with an orbital period of 11.3 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. Mutual gravitational tugs between the planets can slowly reshape their orbits, preserving clues to the system's assembly.
