K2-406 b: A Jupiter-Like World Orbiting a Sun-Like Star
K2-406 is a G4 star located 278 light-years from Earth. It has a mass of 0.798 solar masses, a radius of 0.961 solar radii, and a temperature of 5780 K. One planet is known to orbit this host.
That planet, K2-406 b, was discovered by the transit method in 2022. A transit occurs when a planet passes in front of its star from our viewpoint, causing a small dip in observed brightness. K2-406 b completes an orbit every 22.5 days and has a radius of 4.6 Earth radii, larger than Earth's. With a radius exceeding 4 times Earth's, it is classified as Jupiter-like.
