Kepler-409b is a super-Earth orbiting Kepler-409, a G-type main-sequence star. Its orbital period around the star is 69 days. Kepler-409b has a radius 1.199 times that of Earth and a mass 6 times that of Earth. Its discovery in 2014 was made through the use of the transit detection method. The transit method was performed by the Kepler space telescope.[1]
