TOI-763 is a Sun-like G-type star (about 0.92 solar masses, 5,450 K, 0.90 solar radii), 95.1 light-years from Earth. TOI-763 b is a 9.8-Earth-mass planet, with an orbital period of 5.6 days, at 0.060 AU from its star, and an equilibrium temperature near 1,038 K, discovered in 2020 via transit. TOI-763 c is a 9.3-Earth-mass planet, with an orbital period of 12.3 days, at 0.101 AU from its star, and an equilibrium temperature near 800 K, discovered in 2020 via transit. Mutual gravitational tugs between the planets can slowly reshape their orbits, preserving clues to the system's assembly.
