Kepler-43, formerly known as KOI-135, is a star in the northern constellation of Cygnus. It is located at the celestial coordinates: Right Ascension 19h 00m 57.8034s, Declination +46° 40′ 05.665″. [7] With an apparent visual magnitude of 13.996, [3] this star is too faint to be seen with the naked eye. The Kepler-43 has a very strong starspot activity. [5]
The 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. [8]
The planet nightside temperature was measured to be 2043+79
−352
K.
