Kepler-78 (formerly known as KIC 8435766) is a 12th magnitude star 407 light-years (125 parsecs) away in the constellation Cygnus.[2] Initially classified as an eclipsing binary with orbital period 0.710015 days,[5] it was later re-classified as a single star with significant interaction between star magnetosphere and close-in planet.[6] The radius of the star is of about 74% of the Sun, and the effective temperature is about 5100 K.
