K2-403 and Its Jupiter-Like Planet
K2-403 is a G-type star 804 light-years away with a spectral type of G4. Its mass is 0.784 solar masses and its radius is 0.886 solar radii, smaller than the Sun's, while its temperature of 5510 K is cooler than the Sun's. One planet orbits this host.
That planet, K2-403 b, is Jupiter-like and was discovered by transit in 2022. It completes an orbit every 33.6 days, and its radius of 5.33 Earth radii is larger than Earth's, placing it beyond the radius range of Neptune-like worlds.
