HD 181433 b

HD 181433 b is an extrasolar planet located approximately 87 light years away[4] in the constellation of Pavo, orbiting the star HD 181433. 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]
