Kepler-90e is an exoplanet orbiting the starKepler-90, located in the constellationDraco. It was discovered by theKepler telescope in October 2013. It orbits its parent star at only 0.42astronomical units away, and at its distance it completes an orbit once every 91.94 days.[1]
The planet orbits aG-type star namedKepler-90, its host star. The star is 1.2 times as massive as theSun and is 1.2 times as large as the Sun. It is estimated to be 2 billion years old, with a surface temperature of 6080K. In comparison, the Sun is about 4.6 billion years old[2] and has a surface temperature of 5778 K.[3]
