Planet b

On October 15, 2001, the planet was found orbiting the star. It is one of the most massive planet ever discovered. It orbits in a very eccentric orbit and takes approximately 2064 days (5.65 years) to revolve. Because of its eccentricity that passes through the habitable zone plus a massive superjovian, it would have been disrupted the orbits of Earth-like planets and may have plunged into the star or thrown out into interstellar space.
