According to the source at the bottom of the article (http://www.space.com/scienceastronomy/relic_star_021030.html) it is a low mass star.Jan Lapère 16:53, 28 September 2005 (UTC)

It is a low mas star, but it is also very old. Therefore it has become a giant. Star doesn't have to be massive to become a giant, term 'giant' refers to an evolutionary phase of stars. Star becomes a giant when the hydrogen fusion ends in its core and it starts to swell.--Jyril 17:18, 28 September 2005 (UTC)
With an age of around 13 billion years, this red giant star ought to have a mass of about 70% of the mass of our Sun.

All single stars with masses lower than these 70% of the Sun have a life time superior to the age of the Universe. --Siffler 17:31, 2 February 2006 (UTC)
