WASP-89 is a K3 star located 949 light-years away, with a mass of 0.92 solar masses and a radius of 0.88 solar radii. Its temperature is 5130 K, cooler than the Sun's, and its reported radius estimate is smaller than the Sun's. The star is 1.3 billion years old. One planet orbits this host.
WASP-89 b is a Jupiter-like planet discovered by transit in 2015. Its radius is 11.7 Earth radii, larger than Earth's, and its mass is 1880 Earth masses, larger than Earth's and roughly 5.9 times Jupiter's mass. The planet completes an orbit in 3.36 days. Its mean density is 6.52 g/cm³, 1.18 times Earth's.
