:INFO Gas giant around WASP-33 It is 1.59 times Jupiter's radius, closest in size to Jupiter, and 665.2 times Earth's mass, at 0.69 g/cm3, less dense than Earth. A year there lasts 1.22 days, on an orbit 16 times closer to its star than Mercury is to the Sun. Its equilibrium temperature is 2782 K, hotter than the surface of many stars. The host star WASP-33 runs at 7430 K with 1.50 times the Sun's mass. :STATS [icon:TARGET] Radius | 17.86 Earth radii [icon:CHART] Mass | 665.2 Earth masses [icon:FIRE] Equilibrium temperature | 2782 K (measured) [icon:CLOCK] One year | 1.22 days [icon:BOLT] Orbit radius | 0.0239 AU [icon:STAR] Host star | WASP-33 at 7430 K [icon:USERS] Distance | 398 light-years [icon:TRENDING_DOWN] Starlight blocked | 1.282% at each transit :COUNTER 2782 K: hot enough to vaporise rock on the dayside :PATH What you get from the shadow How deep the star dims fixes the planet's size relative to it. :NOTE Found by SuperWASP in 2010. :NOTE Size from the shadow, mass from elsewhere. Most transiting planets never get the second half, and without it composition stays a guess. :LINK https://exoplanetarchive.ipac.caltech.edu/overview/WASP-33%20b NASA Exoplanet Archive: source data, including the values not used here
