Pi-1

Southern polar star

Its story

Pi-1 Octantis is a yellow star at 394 light-years, set in the constellation that wraps around the south celestial pole. In that region, where no bright star marks the south, each modest star of the Octant takes on a cartographic role: small beacons that helped sailors for centuries triangulate the invisible southern axis. Pi-1 is one of those beacons — nearly anonymous, yet necessary.
