WASP-80 b: A Transiting Jupiter-like Planet Around a Cool Dwarf
WASP-80 is a K7 V star, a cool main-sequence dwarf, located 162 light-years away. Its mass is 0.57 solar masses and its radius is 0.571 solar radii, both smaller than the Sun's, and its temperature of 4150 K is cooler than the Sun's. One planet orbits this host.
That planet is WASP-80 b, a Jupiter-like world discovered by the transit method in 2012. It has a mass of 171 Earth masses and a radius of 11.2 Earth radii, both larger than Earth's. Its orbital period is 3.07 days, and its mean density is 0.671 g/cm³, 0.122 times Earth's.
