WASP-147 and Its Jupiter-Like Planet

WASP-147 is a G4 star 1420 light-years away, with 1.04 solar masses, 1.43 solar radii, a temperature of 5700 K, and an age of 8.47 billion years. Its reported radius estimate is larger than the Sun's. One planet orbits this host.

That planet is WASP-147 b, a Jupiter-like world discovered by transit in 2018. Its radius of 12.5 Earth radii exceeds 4 times Earth's radius and is larger than Earth's, while its mass of 87.4 Earth masses is also larger than Earth's.

WASP-147 b completes an orbit every 4.6 days. Its mean density is 0.247 g/cm³, 0.0448 times Earth's, a consequence of its inflated size relative to its mass.
