Alpha Mensae

Alpha Mensae, also named Hoerikwaggo, is the brightest star in the constellation Mensa. At a magnitude of 5.09, it is the dimmest lucida (a constellation's brightest star) in the sky, and the second-faintest star labeled "alpha", after Alpha Octantis. Due to its declination, on Earth it is best visible from higher latitudes of the southern hemisphere, yet can also be seen, though low in the sky, from just north of the Equator when near its daily arc's highest point, the culmination. It is 33 light-years away from the Solar System. Alpha Mensae is a G-type main sequence star, forming a binary star system with a red dwarf companion.
