The brightest star is v Oct with an RA of 21h 41m 28.47s and declination of −77° 23′ 22.1″
The southern circumpolar constellation that contains the stellar south pole is called Octans. It is a faint constellation located close to the south celestial pole, making it useful for navigation in the Southern Hemisphere. Octans is named after the octant, a navigational tool used for determining latitude that was the precursor to the modern sextant.
The stellar south pole is located in the constellation Octans. This constellation is relatively faint and is situated in the southern celestial hemisphere. The south celestial pole itself is not associated with any bright stars, but Octans contains the star Sigma Octantis, which is the closest star to the south celestial pole.
The constellation you are referring to is Octans. It is often associated with the navigational tool known as the Octant, which was used before the invention of the sextant for celestial navigation. Octans is not very well-known because it is located far in the southern hemisphere and is not visible from most populated areas in the northern hemisphere.
Currently, the Earth's south pole is pointing towards the constellation of Octans. This constellation is not very well-known, but it is used for celestial navigation as it helps determine the location of the south celestial pole.
The southern circumpolar constellation that contains the stellar south pole is Crux, also known as the Southern Cross. It is a prominent asterism in the southern hemisphere sky and is easily recognizable by its distinctive shape of four bright stars. Due to its proximity to the celestial south pole, Crux remains visible all year round in the southern sky.

Octans (the octant).
The stellar south pole is located in the constellation Octans. This constellation is relatively faint and is situated in the southern celestial hemisphere. The south celestial pole itself is not associated with any bright stars, but Octans contains the star Sigma Octantis, which is the closest star to the south celestial pole.
The earth's south pole points into a big dark patch of sky, completely undistinguished by the presence of anything worth looking at with the naked eye. The nearest constellation is Octans, a triangle of dim stars, the brightest of which has a magnitude of 3.8 (dim). Aside from Octans, there isn't another named constellation, and hardly an easily visible star, within 10 degrees of the celestial pole. (About 20 times the size of the full moon.) Certainly nothing like the North Star to offer the slightest aid to navigation. Pretty disappointing.

No. Sigma Octans is a star close to the south pole of the sky, but it is not particularly bright.
Yes, Polaris in Ursa Minor is the "North Star" located using the stars of the Big Dipper (Ursa Major). It is currently the closest bright star to the celestial pole, i.e. the point directly above the Earth's North Pole. The pole star for the South Pole is currently Sigma Octantis in the constellation Octans.
Most of the "official" star and constellation names were created by the Greek, Roman and Arab astronomers before about 1400. (Much of the Greek and Roman astronomical knowledge was lost during the "Dark Ages", and survived only because of Arabic translations from the earlier texts.) So many star names and constellation names are of Greek, Roman and Arabic origin. Most of the constellations were visible from the latitudes of Greece, Europe and Egypt, and were derived from animals, gods and heroes. Starting in the 1500s and afterward, European seafarers sailing the southern oceans found new stars and new constellations not visible from the northern hemisphere. Many of the constellation names they created were of nautical or technical origin, such as "Telescopium", "Microsopium", "Octans" and "Sextans". The constellation Fornax in the southern hemisphere is named for the Furnace.
There are many constellations visible in the night sky in the southern hemisphere. What you see will ultimately depend upon your location and the season. Those that are southern circumpolar constellations can be seen all year round. Southern Circumpolar Constellations: Apus, Chamaeleon, Circinus, Crux, Dorado, Hydrus, Mensa, Musca, Norma, Octans, Pavo, Triangulum Australe, Tucana, Volans
The sailors who named most of the southern hemisphere constellations looked up and imagined shapes in the stars; and since they were sailors, they imagined nautical objects, like the Octant, the Compass, the Telescope, the Flying Fish, and the Stove.Octans, the Octant, represents a navigational instrument that is one-eighth of a circle. The octant wasn't big enough for detailed navigation, so a bigger instrument that was one-sixth of a circle - the "sextant" - replaced it.
