K2-161 and Its Jupiter-Like Planet
K2-161 is a star located 2990 light-years away. It has 0.987 solar masses and a radius of 2.57 solar radii, making its reported radius estimate larger than the Sun's. Its temperature is 4970 K, cooler than the Sun's. One planet orbits this host.
That planet is K2-161 b, a Jupiter-like world discovered by transit in 2018. A transit occurs when a planet passes in front of its star from our viewpoint, causing a small dip in observed brightness. K2-161 b has a radius of 6.12 Earth radii, larger than Earth's, and an orbital period of 9.28 days. Its size classification reflects radius, not composition.
