:INFO Gas giant around Ross 458 It is 1.25 times Jupiter's radius, closest in size to Jupiter, and 1907.0 times Earth's mass. :STATS [icon:TARGET] Radius | 14.01 Earth radii [icon:CHART] Mass | 1907.0 Earth masses [icon:BOLT] Orbit radius | 1100.0000 AU [icon:USERS] Distance | 38 light-years :CHECKLIST Known and unknown, as the archive has it [ ] A measured radius. Yes. [ ] A measured mass. Yes. [ ] A density, which decides rock or gas. No. [ ] A semi-major axis. Yes. [ ] A temperature someone observed rather than calculated. No. [ ] An eccentricity, so the orbit shape is known. No. :PATH What seeing it actually provides Photons from the planet itself rather than an inference from the star. :NOTE Found by Las Campanas Observatory in 2010. :NOTE This is one of the rare planets that has actually been photographed. Fewer than a hundred of the thousands known were found this way, and they are mostly young giants far from their stars. :THREAD :LINK https://exoplanetarchive.ipac.caltech.edu/overview/Ross%20458%20c NASA Exoplanet Archive: every published measurement of this planet
