KIC 8121913 b: A Distant Star and Its Close-Orbiting Planet
KIC 8121913 is a star 2310 light-years away. Its mass is 1.46 solar masses, its radius is 2.23 solar radii, and its temperature is 5980 K, so it is more massive, larger, and hotter than the Sun. One known planet orbits this host.
That planet is KIC 8121913 b, discovered in 2021 through orbital brightness modulation. Its minimum mass is 667 Earth masses, or roughly 2.1 times Jupiter's mass, making its minimum mass larger than Earth's. It completes an orbit every 3.29 days.
