Kepler-43, formerly known as KOI-135, is a star in the northern constellation of Lyra. At 14th magnitude, it is too faint to be seen with the naked eye.
Kepler-43 has a very strong starspot activity.[6]
Planetary system
[edit]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.[4]
The planet nightside temperature was measured to be 2,043+79
−352 K.[6]
