Kepler-78
Sign in to saveKepler-78 (formerly known as KIC 8435766) is a 12th magnitude star away in the constellation Cygnus. Initially classified as an eclipsing binary with orbital period 0.710015 days, it was later re-classified as a single star with significant interaction between star magnetosphere and close-in planet. The radius of the star is of about 74% of the Sun, and the effective temperature is about .

Kepler-78 (formerly known as KIC 8435766) is a 12th magnitude star away in the constellation Cygnus. Initially classified as an eclipsing binary with orbital period 0.710015 days, it was later re-classified as a single star with significant interaction between star magnetosphere and close-in planet. The radius of the star is of about 74% of the Sun, and the effective temperature is about .
==Planetary system== The Kepler-78 planetary system is composed of one known planet called Kepler-78b, a planet slightly bigger than Earth with an extremely close orbit to the parent star. The orbital period of this planet is about 8.5 hours because of its proximity to its star. While it has a similar density to the Earth (at 5.57 g/cm3), its surface temperature is about 1300 to 1500 K.
