Gam-2

Southern polar star

Its story

Gamma-2 Octantis lies 305 light-years away, in the constellation that holds the south celestial pole: the Octant, where no bright polar star answers the one in the north. It is a K0 III orange giant, ten and a half times the Sun's radius, fifty-two times its light, receding at 27 km/s. A warm light that wheels with extreme slowness around an empty point in the sky — the true southern axis of the visible universe.
