description Kepler-90d Overview
Kepler-90d is a confirmed Neptune-like exoplanet in the Kepler-90 system, orbiting a G-type star. NASA lists a mass of 8.6 Earths, a radius of 0.256 Jupiter radii, an orbital distance of 0.32 astronomical units, and a 59.7-day period. It was detected by the transit method, meaning it was identified from the small dip in starlight produced when the planet passed in front of its host star, and its discovery was announced in 2013.
