Alp

Its story

Alpha Octantis is an eclipsing binary system: two near-identical F stars orbiting each other every nine days or so, mutually covering each other's light every 2.88 days in a dance of eclipses visible from Earth. She lives in Octans, the constellation framing the southern celestial pole, in a corner of sky where no bright southern pole star exists. At 142 light-years, she is a pair turning in silence on an invisible axis.
