What is 12 Librae

12 Librae is a K-type orange giant 417 light-years away, set inside the beam of the Scales. Coppery and calm, it has already crossed the border between stellar maturity and expansive old age. Its light started its journey while Renaissance Europe was still rummaging through Arab libraries for ancient star catalogues. It arrives tonight warm, almost melancholic.
