Kepler-468 is a Sun-like G-type star (about 0.96 solar masses, 5,498 K, 0.87 solar radii), 443 light-years from Earth. Kepler-468 b is a planet with 13.3 Earth radii, with an orbital period of 38.5 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. The planet's large radius (13.3 Earth radii) indicates a bloated atmosphere heated by intense stellar radiation. Repeated transit observations constrain the planet's orbital inclination and stellar density, anchoring the system's physical scale.
