WASP-132: A K-Type Dwarf and Its Three Known Planets

WASP-132 is a K4 V star, a spectral type that marks it as somewhat cooler than the Sun, located 401 light-years away. It has three known planets. The star's reported mass estimate is 0.789 solar masses and its radius estimate is 0.758 solar radii, both smaller than the Sun's, and its temperature of 4690 K is cooler than the Sun's. Its age is 7.2 billion years.

WASP-132 b is a Jupiter-like planet discovered by transit in 2016. It has a mass of 136 Earth masses and a radius of 10.1 Earth radii, both larger than Earth's, with a mean density of 0.728 g/cm³, 0.132 times Earth's. Its orbital period is 7.13 days, the second-shortest among the listed planets.

WASP-132 c is a Super-Earth discovered by transit in 2022. Its mass is 6.26 Earth masses and its radius is 1.84 Earth radii, both larger than Earth's, and its mean density is 5.53 g/cm³, 1 times Earth's. It orbits in 1.01 days, the shortest period among the listed planets.

WASP-132 d was discovered in 2024 using the radial velocity method, which measures the wobble a planet's gravity induces in its star's motion. Its minimum mass is 1640 Earth masses, a lower bound on its true mass and roughly 5.16 times Jupiter's mass, also larger than Earth's. Its orbital period is 1820 days, the longest among the listed planets.
