Gam

Its story

Gamma Reticuli is a cool M4 red giant, swollen to 115 times the Sun's radius and radiating 1,846 times more energy despite its 3,450-kelvin surface. At 470 light-years it pulsates over a brief period inside a long-period variable pattern. It is the reddest star of Reticulum, the little Net charted by Lacaille in the eighteenth century to honour the reticle of his telescope.
