pi Men b
pi Men b
pi Men b is an exoplanet orbiting the star pi Men, located about 59.6 light-years (18.3 pc) away from Solar System. Its discovery was publicly announced on 2001.
The host star pi Men has apparent magnitude of 5.7, with absolute magnitude of 4.4. It is 1.1 times more massive and 1.1 times bigger compared with our Sun. The surface temperature is 6037 with its spectral types of G0V
In this planetary system, the extrasolar planet pi Men b orbits around the star pi Men every 2088.3 days with its orbital distance of 3.31 AU ( 494869756.3 km)
(Projected orbit of pi Men b around its host star pi Men)
The Star pi Men 's habitable zone is located at the following distance
