Eta 2 Dorado
Cool red starWhat is Eta 2 Dorado
Eta-2 Doradus is a red giant at 641 light-years, lit in a southern constellation that most Europeans will never have the chance to see in their lifetime. Its reddish hue marks a cool surface and a vast atmosphere, swollen at the end of its nuclear life. It glows quietly near the Large Magellanic Cloud, in a region of sky that knows very little human history.
