Added apparent magnitude info
'''Gliese 581''', also known as '''HO Librae''', is a red dwarf star around 20.4 [[light year|light years]] away, which is most famous for the discovery of the [[Gliese 581c|first low mass planet within a star's habitable zone]]. In total, four planets have thus been found orbiting the star, two of which may sit within the [[habitable zone]].

Despite being only 20 light years distant, because Gliese 581 is a red dwarf, and thus dim, it has an apparent magnitude of only 10.56 and thus invisible to the unaided eye.
