Kepler-409b
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 that is 1.199 that of Earth and a mass of 6 that of Earth. It's discovery in 2014 was made through the use of a transit detection method of Kepler-409. The transit method was performed by the Kepler space telescope. [1]
