:INFO Terrestrial around Kepler-1994 It is 0.51 times Earth's radius, closest in size to Mars. A year there lasts 4.61 days, on an orbit 7 times closer to its star than Mercury is to the Sun. Its equilibrium temperature is 1032 K, hot enough to melt lead. The host star Kepler-1994 runs at 5495 K with 0.93 times the Sun's mass. :STATS [icon:TARGET] Radius | 0.51 Earth radii [icon:FIRE] Equilibrium temperature | 1032 K (measured) [icon:CLOCK] One year | 4.61 days [icon:BOLT] Orbit radius | 0.0530 AU [icon:STAR] Host star | Kepler-1994 at 5495 K [icon:USERS] Distance | 789 light-years [icon:TRENDING_DOWN] Starlight blocked | 0.002% at each transit :PATH What the transit gives The fraction of starlight blocked sets the radius against the star's. :COUNTER 0.51x Earth: smaller than Venus :CHECKLIST The state of the record for this planet [ ] A size. Yes. [ ] A mass. No. [ ] A density, the one clue to composition. No. [ ] How far out it orbits. Yes. [ ] An observed temperature. Yes. [ ] An eccentricity, so the orbit shape is known. Yes. :NOTE Found by Kepler in 2023. Kepler stared at one patch of sky for four years, which is why so many of its planets have short periods: a planet only counts once you have seen it cross several times. :NOTE Everything known here comes from how much light went missing. That fixes the size and leaves the mass entirely open. :LINK https://exoplanetarchive.ipac.caltech.edu/overview/Kepler-1994%20b NASA Exoplanet Archive: the full record for Kepler-1994 b
