The apparent magnitude is 5.67, which can be visible to the naked eye in exceptionally dark, clear skies.
The star is slightly larger than the Sun in terms of mass, size, luminosity, temperature and metallicity, and is about 730 million years younger.
[7] Pi Mensae b is one of the most massive planets ever discovered, and has a very eccentric orbit that takes approximately 2,151 days (5.89 years) to complete.
Because of its eccentricity, and being a massive brown dwarf that passes through the habitable zone, it would have disrupted the orbits of any Earth-like planets, and possibly thrown them into the star, or out into the interstellar medium.
[10] This was confirmed two days later, where the attention was called that the system is amenable for future planet atmospheric studies.
