Zet

Its story

Zeta Octantis is a yellow-white F0 giant with poor metallicity, only 44% of the Sun's heavy elements, an inheritance from its 1.25-billion-year age. 162 light-years away, it circles silently around the south celestial pole, that lonely region of the sky lacking a bright pole star like the north's. There, where Earth's rotation traces tiny circles, it joins the slow austral spin.
