Pi Mensae b has a very eccentric orbit and takes 5.89 years to revolve around the star. The semi-major axis of the planet to the star is 3.38 AU while the semi-minor axis is 2.59 AU. This planet passes through the star's habitable zone at periastron (1.21 AU) while at apastron, it passes to beyond Jupiter-Sun distance (5.54 AU). The gravitational influence of this planet would disrupt the orbit of any potentially Earth-like planet. Pi Mensae b is over ten times more massive than Jupiter, the most massive planet in our solar system. It will have 10 times the surface gravity of Jupiter
IAU definition of planet planets. Mike Brown, the discoverer of Sedna and Eris, has said that at least 53 known bodies in the Solar System probably fit the definition, and that a complete survey would probably reveal more than 200. The definition would have considered a pair of objects to be a double planet system if each component independently satisfied the planetary criteria and the common center of gravity of the system (known as the "barycenter") was located outside of both bodies. Pluto and Charon would have been the only known double planet in the Solar System. Other planetary satellites (like Earth and its
