WASP-173 A b: A Jupiter-like Planet in a Close Orbit
WASP-173 A is a G2 star 760 light-years away, with measurements including an age of 3.25 billion years, a mass of 1.09 solar masses, a radius of 1.1 solar radii, and a temperature of 5770 K. Its reported mass and radius estimates are both larger than the Sun's. One planet is known to orbit this star.
WASP-173 A b is a Jupiter-like planet discovered by transit in 2018. Its radius of 13.5 Earth radii is larger than Earth's, and its mass of 1170 Earth masses is also larger than Earth's - roughly 3.69 times Jupiter's mass. Its mean density is 2.66 g/cm³, 0.482 times Earth's. The planet completes an orbit in 1.39 days.
