Location of Gaia 1 (circled)
Gaia 1 is an
half-light radius is about 29 light-years (9 pc), assuming a distance of 15,000 light-years (4,600 pc), and it has an estimated mass of about 22,000 M☉.[1]
The Gaia 1 cluster was detected by researchers applying automated
red giant branch and a pronounced red clump that allows the absolute magnitude of the stars to be deduced and the distance calculated. Fitting the red giant branch also allows the age of the cluster to be calculated at 6.3 billion years.[1]
