WASP-107 and Its Two Known Planets
WASP-107 is a K6 star 211 light-years away with two known planets. The star is 3.4 billion years old, has a mass of 0.683 solar masses, a radius of 0.67 solar radii, and a temperature of 4430 K. Its mass and radius are smaller than the Sun's, and its temperature is cooler.
WASP-107 b was discovered by transit in 2017. It is a Jupiter-like planet with a radius of 10.5 Earth radii, larger than Earth's, and a mass of 33 Earth masses, also larger than Earth's. Its orbital period is 5.72 days, the shortest among the listed planets. Its mean density is 0.158 g/cm³, 0.0287 times Earth's.
WASP-107 c was discovered by radial velocity in 2020. Its orbital period is 1090 days, the longest among the listed planets.
