:INFO Mini-neptune around HD 136352 It is 2.92 times Earth's radius, closest in size to Neptune, and 11.2 times Earth's mass, at 2.50 g/cm3, less dense than Earth. A year there lasts 27.59 days, on an orbit 2 times closer to its star than Mercury is to the Sun. Its equilibrium temperature is 677 K, hotter than any desert. The host star HD 136352 runs at 5664 K with 0.87 times the Sun's mass. :JOURNEY HD 136352 from the inside out 1 0.096 AU 2 0.172 AU 3 0.425 AU :STATS [icon:TARGET] Radius | 2.92 Earth radii [icon:CHART] Mass | 11.2 Earth masses [icon:FIRE] Equilibrium temperature | 677 K (measured) [icon:CLOCK] One year | 27.59 days [icon:BOLT] Orbit radius | 0.1721 AU [icon:STAR] Host star | HD 136352 at 5664 K [icon:USERS] Distance | 48 light-years :PATH What the wobble gives A minimum mass, from how fast the star moves toward and away from us. :NOTE This planet was found by the wobble it induces in its star, which measures mass rather than size. A radius quoted for such a planet usually comes from a later transit or from a model. :NOTE Found by La Silla Observatory in 2019. :NOTE HD 136352 has 3 known planets. Multi-planet systems are where orbital dynamics can be measured rather than assumed. :LINK https://exoplanetarchive.ipac.caltech.edu/overview/HD%20136352%20c Every parameter ever published for HD 136352 c, at the NASA Exoplanet Archive
