WASP-161 and Its Jupiter-Like Planet
WASP-161 is a star located 1120 light-years away. It has a mass of 1.39 solar masses, a radius of 1.71 solar radii, and a temperature of 6400 K, each estimate larger or hotter than the corresponding solar value.
One planet orbits this host: WASP-161 b, a Jupiter-like world discovered by transit in 2018. Its radius of 12.8 Earth radii exceeds Earth's, and its mass of 791 Earth masses is roughly 2.49 times Jupiter's mass and larger than Earth's. The planet completes an orbit every 5.41 days, and its mean density is 2.07 g/cm³, 0.376 times Earth's.
