:INFO Gas giant around HATS-70 It is 1.38 times Jupiter's radius, closest in size to Jupiter, and 4100.0 times Earth's mass, at 6.64 g/cm3, denser than Earth. A year there lasts 1.89 days, on an orbit 11 times closer to its star than Mercury is to the Sun. Its equilibrium temperature is 2730 K, hotter than the surface of many stars. The host star HATS-70 runs at 7930 K with 1.78 times the Sun's mass. :STATS [icon:TARGET] Radius | 15.51 Earth radii [icon:CHART] Mass | 4100.0 Earth masses [icon:FIRE] Equilibrium temperature | 2730 K (measured) [icon:CLOCK] One year | 1.89 days [icon:BOLT] Orbit radius | 0.0363 AU [icon:STAR] Host star | HATS-70 at 7930 K [icon:USERS] Distance | 4758 light-years [icon:TRENDING_DOWN] Starlight blocked | 0.570% at each transit :COUNTER 2730 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 A transit gives the radius and a separate measurement gives the mass. Having both is what makes a density, and a density is the only clue to composition at this range. :NOTE Found by HATSouth in 2019. :LINK https://exoplanetarchive.ipac.caltech.edu/overview/HATS-70%20b NASA Exoplanet Archive: source data, including the values not used here
