This planet has mass at least 7.56 times that of Earth. This planet is classified as a super-Earth and orbits at 0.080 AU and varies only about 0.063 AU with an eccentricity of 0.396.[3] François Bouchy et al. have published a paper detailing the HD 181433 planetary system in Astronomy and Astrophysics.[1] References1. ^1 {{cite journal | title=The HARPS search for southern extra-solar planets.
