PI MENSAE B

'Pi Mensae b' is a long-period supermassive planet that orbits around Pi Mensae.
On October 15, 2001, a team of astronomers including Jones, Butler, Tinney, Marcy, Penny, McCarthy, Carter, and Pourbaix announced the discovery of one of the most massive planet have ever been discovered. It was discovered by Anglo-Australian Planet Search team that used doppler spectrometer mounted on the Anglo-Australian Telescope.
Pi Mensae b orbits in a very eccentric orbit and takes 5.89 years to revolve around Pi Mensae. The semi-major axis of the planet to the star is 3.38 AU while semi-minor axis is 2.60 AU. This planet passes through habitable zone at periastron distance while at apastron, it passes through Jupiter-Sun distance (5.2 AU). Passage to habitable zone would disrupt the orbit of any potentially Earth-like planet.
The planet is over ten times more massive than Jupiter, the most massive planet in our solar system. The inclination of the orbit is not known, and this planet could be a brown dwarf instead.
