WASP-189 and Its Giant Planet

WASP-189 is a star 325 light-years away with one known planet. The star is 0.73 billion years old and has a mass of 2.07 solar masses, a radius of 2.36 solar radii, and a temperature of 8000 K. Its reported mass, radius, and temperature estimates are all larger or hotter than the Sun's.

The planet WASP-189 b is Jupiter-like, discovered in 2020 by the transit method, in which a planet passes in front of its star from our viewpoint, causing a small dip in observed brightness. It orbits every 2.72 days. Its radius of 18.1 Earth radii is larger than Earth's, and it exceeds four times Earth's radius, which is the threshold for the Jupiter-like class. Its mass of 632 Earth masses is also larger than Earth's and roughly 1.99 times Jupiter's mass. Its mean density is 0.583 g/cm³, 0.106 times Earth's.
