In the cosmological model of a billions of years old universe, astronomers have calculated the star to be between 2 and 4.3 billion years old,<ref name="exo">http://exoplanet.eu/star.php?st=Gl+581</ref> using measurements of Gliese 581’s kinematic characteristics and magnetic activity. More recent measurements of the star shows its brightness only varies slightly over time, suggesting it is even older.<ref>http://www.astronomy.com/asy/default.aspx?c=a&id=5619</ref>
