K2-140 b: A Jupiter-like Planet Around a Sun-like Star
K2-140 is a G5 star located 1130 light-years away. It has a mass of 1 solar masses, a radius of 0.987 solar radii, a temperature of 5650 K, and an age of 4.22 billion years. Its radius is smaller than the Sun's, and its temperature is cooler than the Sun's. One planet orbits this host.
That planet is K2-140 b, a Jupiter-like world discovered by transit in 2017. It completes an orbit every 6.57 days. Its mass is 296 Earth masses and its radius is 13.6 Earth radii, both larger than Earth's. Its mean density is 0.653 g/cm³, 0.118 times Earth's.
