WASP-166 and Its Jupiter-Like Planet

WASP-166 is a star 372 light-years away with a spectral type of F9 V, indicating a main-sequence dwarf somewhat hotter and more massive than the Sun. Its mass is 1.19 solar masses, its radius is 1.22 solar radii, and its temperature is 6050 K. The star is 2.1 billion years old.

One planet orbits this host: WASP-166 b, a Jupiter-like world discovered by the transit method in 2019. Its radius is 7.06 Earth radii, larger than Earth's, which places it well beyond the Jupiter-like threshold for size class. Its mass is 32.1 Earth masses, also larger than Earth's. The planet completes an orbit every 5.44 days. Its mean density is 0.502 g/cm³, 0.0912 times Earth's.
