'''Kepler-90e''' is an exoplanet orbiting the star [[Astronomy:Kepler-90|Kepler-90]], located in the constellation [[Astronomy:Draco (constellation)|Draco]]. It was discovered by the ''[[Engineering:Kepler (spacecraft)|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.<ref name=Cabrera/>

==Host star==
{{main|Astronomy:Kepler-90}}
The planet orbits a [[Astronomy:Stellar classification#Class G|G-type]] star named [[Astronomy:Kepler-90|Kepler-90]], its host star. The star is 1.2 times as massive as the [[Astronomy:Sun|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 [[Kelvin|K]]. In comparison, the Sun is about 4.6 billion years old<ref>{{cite web |url=http://www.universetoday.com/18237/how-old-is-the-sun/ |title=How Old is the Sun? |author=Fraser Cain |date=16 September 2008 |publisher=Universe Today |access-date=19 February 2011}}</ref> and has a surface temperature of 5778 K.<ref>{{cite web |url=http://www.universetoday.com/18092/temperature-of-the-sun/ |title=Temperature of the Sun |author=Fraser Cain |date=15 September 2008 |publisher=Universe Today |access-date=19 February 2011}}</ref>
