What is Epsilon Circinus

Epsilon Circini is an orange giant in one of the most modest constellations of the southern sky, all but reclining against the brilliance of Alpha Centauri. At 408 light-years, it stands well beyond its hotter, younger neighbours in evolution: a star that has already burned through its main hydrogen and now glows with the slow, almost ruddy radiance of the giant phase.

Where it is and when to see it

Epsilon Circinus lies in the southern celestial hemisphere. It is visible to the naked eye under a dark sky. Its best month of the year is May, when it culminates around midnight.
