Sign in to saveKepler-90i (also known by its Kepler Object of Interest designation KOI-351.08) is a super-Earth exoplanet with a radius 1.32 times that of Earth, orbiting the early G-type main sequence star Kepler-90 every 14.45 days, discovered by NASA's Kepler spacecraft. It is located about 2,840 light-years (870 parsecs, or nearly km) from Earth in the constellation Draco. The exoplanet is the eighth in the star's multiplanetary system.

Kepler-90i (also known by its Kepler Object of Interest designation KOI-351.08) is a super-Earth exoplanet with a radius 1.32 times that of Earth, orbiting the early G-type main sequence star Kepler-90 every 14.45 days, discovered by NASA's Kepler spacecraft. It is located about 2,840 light-years (870 parsecs, or nearly 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.
==Characteristics== ===Mass, radius and temperature=== Kepler-90i is a super-Earth exoplanet with a radius of 1.32 , indicating that it is small enough to be rocky. With an Earth-like composition, Kepler-90i would have a mass of about 2.3 , since its volume is 1.32^3 \approx 2.3 times that of Earth's. It has an equilibrium temperature of , similar to the average temperature of Venus.
