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