Kepler-90i (also known by its Kepler Object of Interest designation KOI-351.08)[2] is a super-Earth exoplanet with a radius 1.32[2] times that of Earth, orbiting the early G-type main sequence star Kepler-90 every 14.45 days, discovered by NASA's Kepler spacecraft.[1][3] It is located about 2,840 light-years (870 parsecs, or nearly 2.4078×1016 km) from Earth in the constellation Draco. The exoplanet is the eighth in the star's multiplanetary system. As of December 2017, Kepler-90 is the star hosting the most exoplanets found. Kepler-90i was found with the transit method, in which the dimming effect that a planet causes as it crosses in front of its star is measured, and by a newly utilized computer tool, deep learning, a class of machine learning algorithms.[1][4][5]
