Intro and Visual description
Octans the Octant is devoid of bright stars, but three faint stars (not numbered by brightness) make a small triangle.
The south celestial pole actually lies within Octans. No RA (visible anytime).
The nearest easy-to-spot star to the south pole is Beta-Hydri in Hydrus the Little Snake. No brighter star than Achernar (alpha-Eridani) is closer to the south celestial pole, which lies midway between Achernar (Eridanus) and Crux.
One of 17 constellations created by Nicolas Louis de Lacaille in 1756.
Sigma-Octantis, the closest naked-eye star to the south celestial pole. Magnitude: 5.5 (faint). Distance: 121 LY. Declination: -88 degrees 57 minutes 21 seconds. (Is it closer to the south pole than Polaris is to the north pole?)
