Kepler-616 is a Sun-like F-type star (about 1.06 solar masses, 6,004 K, 0.98 solar radii), 946 light-years from Earth. Kepler-616 b is a planet with 2.4 Earth radii, with an orbital period of 10.0 days, discovered in 2016 via transit. Kepler-616 d is a planet with 2.7 Earth radii, with an orbital period of 51.1 days, discovered in 2021 via transit. Kepler-616 c is a planet with 3.4 Earth radii, with an orbital period of 90.4 days, discovered in 2016 via transit. Mutual gravitational tugs between the planets can slowly reshape their orbits, preserving clues to the system's assembly.
