Pi (π) Mensae (π Men) is a yellow subgiant star in the constellation of Mensa. This star has a high proper motion. The apparent magnitude is 5.67, which can be visible with the naked eye under exceptionally dark, clear sky. It is nearly 60 ly away. The star dwarfs the Sun in terms of mass, size, luminosity, temperature, and metallicity. It is about 730 million years younger than our Sun. This star ranks 100th on the list of top 100 target stars for the planned Terrestrial Planet Finder mission to search for Earth-like planets around the star.

Planet b

On October 15, 2001, the planet was found orbiting the star. It is one of the most massive planets 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.
