WASP-156 b: A Jupiter-Like Planet Orbiting a Cool Dwarf
WASP-156 is a K3 star 398 light-years away, with a mass of 0.842 solar masses and a radius of 0.76 solar radii. Its temperature is 4910 K, and it is 6.4 billion years old. The star's reported mass and radius estimates are smaller than the Sun's, and its reported temperature is cooler than the Sun's. One planet is known to orbit this host.
WASP-156 b is a Jupiter-like planet discovered in 2017 by the transit method. It has an orbital period of 3.84 days, a radius of 6.15 Earth radii, and a mass of 42 Earth masses. Its reported radius and mass estimates are larger than Earth's, and its mean density is 0.995 g/cm³, 0.181 times Earth's.
