WASP-129 b: A Jupiter-like World in a Two-Star System
WASP-129 is a G1 star located 983 light-years away. It is 1 billion years old, has a mass of 1 solar masses, a radius of 0.9 solar radii, and a temperature of 5900 K. Its reported radius estimate is smaller than the Sun's, while its reported temperature is hotter than the Sun's. This host star is accompanied by one known planet, though the catalog system includes a second star.
WASP-129 b is a Jupiter-like planet discovered by transit in 2016. It completes an orbit in 5.75 days. Its radius of 10.4 Earth radii is larger than Earth's, and its mass of 318 Earth masses is also larger than Earth's. Its mean density is 1.55 g/cm³, 0.281 times Earth's.
