Topic: Polaris Australis


In the News (Fri 1 Jan 10)

  
  Polaris - Wikipedia, the free encyclopedia
At present, Polaris is slightly under 1° away from the pole of rotation (about twice the apparent diameter of the Moon) and hence revolves around the pole in a small circle almost 2° in diameter.
Polaris is due to become an even more accurate pole star in the near future — the distance between Polaris and the pole will reach a minimum (of just under 1/2 degree) in 2100.
Although Polaris is a relatively bright star and is conspicuous since no other stars of similar brightness are close to it, it is nowhere near the brightest; it is actually the 47th brightest star.

 Pole star - Wikipedia, the free encyclopedia
The term the pole star usually refers to the star Polaris (colloquially referred-to as the "north star") which is the current northern pole star.
At the present time, Polaris is the pole star in the northern direction.
Sigma Octantis is the closest star to the south celestial pole, but it is too faint to serve as a useful pole star.

 POLARIS FACTS AND INFORMATION
Polaris (α UMi / α Ursae Minoris / Alpha Ursae Minoris) is the brightest star in the constellation Ursa_Minor.
It is easy to find Polaris by following the line traced from Merak to Dubhe (β and α Ursae Majoris, also known as the Pointers), the two stars at the end of the bowl of the Big_Dipper.

 The Stellar Guide: Octans
Unlike Ursa Minor's Polaris, there is no bright star near the South Pole.
The Octant is a navigational tool used to determine the altitude of a star, and thus one's latitude on the Earth.
The octant was used to measure the position of Polaris innumerable times in the early years of celestial navigation.

The star at the end of the dipper handle is Polaris, the " North " or " Pole Star ".
Polaris can also be found by following a line through the two stars which form the end of the "bowl" of the Big Dipper, a nearby asterism found in the constellation Ursa Major.
The seven stars are the origin of the Latin word septentrion meaning "north," and now found as the adjective septentrional (northern) in French and Spanish, to go with adjectives for the other three directions that refer to the position of the sun.

 Sigma Octantis   (Site not responding. Last check: 2007-11-06)
Its position near the southern celestial pole makes it the southern hemisphere 's counterpart to Polaris, the North Star.
To an observer standing at the South Pole, Sigma Octantis would appear almost motionless and all the other stars in the Southern sky would appear to rotate around it.
However, it is a faint star—at magnitude 5.5 it is barely visible to the naked eye—which makes it a rather poor pole star, especially by comparison to the much brighter and easily visible Polaris.

Only twice during every sidereal day does Polaris accurately define the true north azimuth; the rest of the time it is only an approximation and must be corrected using tables.

The star Polaris, the Pole Star, can be found by measuring a line five times the angular distance between the two pointer stars Dubhe and Merak forming the end of the dipper cup, through those stars and up and away from the dipper.
The dipper also points the way to other stars, for instance by sweeping down from the handle one reaches Arcturus (α Boötis) and Spica (α Virginis).
These stars are found along the southwest border of the constellation, the bear's toes.

 Mappa.Mundi Magazine - Locus - Finding the Poles
At this time Polaris in the Little Dipper marks the pole very accurately, since the earth's wobble has moved the north pole to within less than one degree of the star.
They also assumed the South Pole was located in "Terra Australis," an enormous but imaginary continent that balanced the large land masses in the northern hemisphere and was named for Auster, the wind that blew from the south.

 Netherworld - Inf@
Netherworld used to be a project called "Australis" that was a sequel to a story called "polaris" I've been conjuring in my head in tenth grade.
Polaris and Australis were two stories that sorta modeled the visual world of Phillip Pullman's "Dark Materials" trilogy.
Over time, australis ceased to be part of the Polaris story and developed into a story of it's own: Netherworld.

In the Northern hemisphere they have Polaris at a declination of about 89 and a bit degrees to mark the NCP (which is at a declination of 90 degrees).
Here in the South we have Sigma-Octantis (Polaris Australis) which is at a declination of almost -89 degrees, so it tends to very closely circle the SCP.
However, unlike Polaris which is one of the brightest stars in the sky, Sigma-Octantis is very small and dim and not generally visible (if at all) to the unaided eye.

 Proof of Heliocentric Incorrectness 3 - Celestial Poles   (Site not responding. Last check: 2007-11-06)
It cannot be that Polaris is so far away that we would not observe such an effect, for, if that were so, then we definitely would not get any small circle appearing as a result of the World's alleged spin.
Stars in close angular proximity to the north celestial pole, such as Polaris, are not so far away that they do not describe small circles, as a result (so we are told) of the World's rotation about an axis.
We are therefore left with a World that must remain on the north-south axis of the celestial sphere, must be central, because of countless other observations (e.g., Y.P. Varshni's paper, briefly mentioned under " Solar System," elsewhere on this website), and which cannot be a World that rotates.
