WASP-89 b: 1875.2 Earth Masses
Gas giant around WASP-89
It is 1.04 times Jupiter's radius, closest in size to Jupiter, and 1875.2 times Earth's mass, at 7.00 g/cm3, denser than Earth. A year there lasts 3.36 days, on an orbit 9 times closer to its star than Mercury is to the Sun. Its equilibrium temperature is 1120 K, hot enough to melt lead. The host star WASP-89 runs at 5130 K with 0.92 times the Sun's mass.

What the dip tells you
The fraction of starlight blocked sets the radius against the star's.
Size from the shadow, mass from elsewhere. Most transiting planets never get the second half, and without it composition stays a guess.
