Octans (Latin for octant) is an inconspicuous constellation introduced by Nicolas Louis de Lacaille. It is notable mainly as the location of the south celestial pole. Its star Sigma Octantis (σ Oct) is the closest naked-eye star to the pole, but it is so faint that it is practically useless as a polar star for navigation purposes.
