It is located at the celestial coordinates: Right Ascension {{RA|19|00|57.8034}}, Declination {{DEC|+46|40|05.665}}.[4] With an apparent visual magnitude of 13.996,[2] this star is too faint to be seen with the naked eye. Planetary systemThe Kepler spacecraft detected a transiting planet candidate around this star that was confirmed by radial velocity measurements taken by the SOPHIE spectrograph mounted on the 1.93 m telescope at the Haute-Provence Observatory. {{OrbitboxPlanet begin| table_ref = [3] }}{{OrbitboxPlanet | exoplanet = b | mass = 3.23±0.19 | semimajor = 0.0449 | period = 3.024095 | radius_earth = }}{{Orbitbox end}} References1. ^{{citation | contribution=Cygnus – constellation boundary | title=The Constellations | publisher=International Astronomical Union | url=http://www.iau.org/public/constellations/#cyg | accessdate=2011-12-15 }} [5][6]2. ^1 2 3 4 5 6 7 {{citation | title=Kepler-43b | publisher=NASA Ames Research Center | url=http://kepler.nasa.gov/Mission/discoveries/kepler43b/ | accessdate=2011-12-06 }} 3. ^1 {{citation |first1=Jean |last1=Schneider |title=Star: Kepler-43 |work=Extrasolar Planets Encyclopaedia |publisher=Paris Observatory |url=http://exoplanet.eu/star.php?st=Kepler-43 |archive-url=https://archive.is/20140304013802/http://exoplanet.eu/star.php?st=Kepler-43 |dead-url=yes |archive-date=2014-03-04 |accessdate=2011-12-06 }} 4. ^{{cite web |title=Kepler Discoveries |date=2011-12-05 |url=http://kepler.nasa.gov/Mission/discoveries/ }} 5. ^1 2 3 4 5 {{cite DR2}} Gaia Data Release 2 Vizier catalog entry 6. ^1 {{cite journal | title=Stellar Rotation Periods of The Kepler objects of Interest: A Dearth of Close-In Planets Around Fast Rotators | last1=McQuillan | first1=A. | last2=Mazeh | first2=T. | last3=Aigrain | first3=S. | journal=The Astrophysical Journal Letters | volume=775 | issue=1 | at=L11 | year=2013 | arxiv=1308.1845 | bibcode=2013ApJ...775L..11M | doi=10.1088/2041-8205/775/1/L11 }} }}{{Sky|19|00|57.810|+|46|40|05.62}}{{Stars of Cygnus}} 5 : Kepler-43|Cygnus (constellation)|G-type main-sequence stars|Kepler Objects of Interest|Planetary transit variables |
