WASP-133 b: A Jupiter-like Planet in a Close Orbit

WASP-133 is a G4 star 1820 light-years away. It is 6.8 billion years old, has 1.16 solar masses, 1.44 solar radii, and a temperature of 5700 K. Its reported mass and radius estimates are larger than the Sun’s. One planet orbits this host.

WASP-133 b is a Jupiter-like planet discovered by transit in 2016. It has a mass of 369 Earth masses, roughly 1.16 times Jupiter’s mass, and a radius of 13.6 Earth radii. Both its reported mass and radius estimates are larger than Earth’s. Its mean density is 0.814 g/cm³, 0.148 times Earth's. It completes an orbit in 2.18 days.
