IRAS Mosaic of the South Celestial Pole
The infrared sky at the south celestial polar cap is displayed in this image constructed from nine fields of the Infrared Astronomical Satellite (IRAS) Sky Survey Atlas.

 


south celestial pole Point on the celestial sphere directly above the Earth's south pole.
spacetime A synthesis of the three dimensions of space and of a fourth dimension, time; a hallmark of relativity theory.

South Celestial Pole
the point in the sky to which Earth's Geographical South Pole points
spectral class ...

South Celestial Pole (SCP)
A direction determined by the projection of the Earth's South Pole onto the celestial sphere. The SCP is exactly 180 degrees from the North Celestial Pole and corresponds to a declination of -90 degrees.
Southern Hemisphere ...

south celestial pole -- the imaginary point on the celestial sphere directly over the Earth's South Pole.

South Celestial Pole - The point above the Earth's South Pole where the Earth's polar axis, if extended outward into space, would intersect the celestial sphere.

North and South Celestial Poles
The north ands south pivots points around which the sky appears to rotate.

To find the south celestial pole in the sky at this moment, one is less lucky, as that area is a particularly bland portion of the sky, and the nominal south pole star is Sigma Octantis, which with magnitude 5.

celestial pole Either of the two points of intersection of the celestial sphere and the extended axis of the earth, labeled N or S to indicate whether the north celestial pole or the south celestial pole.

The celestial sphere is centered on Earth, and it includes the celestial equator, the north and south celestial poles, and lines of right ascension and declination.

south celestial pole (SCP): projection of the Earth's south pole onto the sky. The SCP altitude = the observer's southern latitude. spacetime the four-dimensional combination of space (three dimensions) and time (the fourth dimension).

One of the closest constellations to the South Celestial Pole (which is held by its neighbor, Octans), Apus (the Bird of Paradise) is also one of the smaller and more obscure.

This point is the South Celestial Pole.
Method two: Canopus and Achernar
The second method uses Canopus (the second brightest star in the sky) and Achernar. Make a large equilateral triangle using these stars for two of the corners.

Plancius instructed Keyser to make observations to fill in the constellation-free zone around the south celestial pole.

Similarly, a Dec of +90 degrees points to the "North Celestial Pole" and -90 degrees points to the "South Celestial Pole." The word Celestial is used to distinguish between, for example, the North Pole in the sky and the North Pole on the Earth.

When using a telescope with an equatorial mount, one aligns the polar axis of the mount with the north or south celestial pole.

Created between 1750-1754 by French astronomer Nicolas Louis de La Caille from stars found near the south celestial pole. The constellation was originally called Mons Mensae.

Celestial pole
the north and south celestial poles are points on the celestial sphere where earths axis of rotation intersects the celestial sphere.

The Bird of Paradise, originally called Avis Indica; a small, faint constellation lying near the south celestial pole, immediately south of Triangulum Australe (the Southern Triangle). See below for details of its brightest stars.

R.A. is one of the co-ordinates used to locate positions on the celestial sphere. Lines run from the North to the South celestial pole and are similar to the Earth's lines of longitude, except that they are measured in units of time.

The effects of precession will take Canopus within 10° of the south celestial pole around the year 14,000 AD.[7] ...

Polaris Australis (Sigma Oct)
Octans was named by Abbé Nicolas Louis de Lacaille. Octans is the constellation which contains the South Celestial Pole. Unlike Ursa Minor's Polaris, there is no bright star near the South Pole.

If the earth's axis is extended, the points where it intersects the celestial sphere are called the celestial poles; the north celestial pole is directly above the earth's North Pole, and the south celestial pole directly above the earth's South ...

Celestial poles Points on the celestial sphere directly above the Earth's poles about which all the stars seem to rotate; known as the north and south celestial poles (NCP and SCP).

Orion, near the June solstice point at the border of the constellations Taurus and Gemini -- shown on this star chart, where the ecliptic intersects the 6-hour meridian extending from the north celestial pole to the south celestial pole.

An imaginary line on the celestial sphere through the north and south celestial poles, passing directly overhead at a given location.
meridian transit
The crossing of the meridian by any astronomical object.

declination: A method of establishing a celestial object's location by using the angular distance north or south of the celestial equator. Similar to a latitude designation on the planet Earth. It is measured from -90o at the south celestial pole to ...

South: one of the cardinal points of the compass, it is the direction opposite north, in the direction of the south celestial pole. It is also the direction of the Sun at local noon (in the northern hemisphere).

Only a planet in an almost polar orbit and situated near the south celestial pole could have escaped his detection. He could have picked up a Neptune-sized planet at seven times the distance of Pluto, or a Pluto-sized planet out to 60 AU.

Continuing his journey towards the south, the north celestial pole sinks below the horizon; the south celestial pole rises above it; or to speak more exactly, the zenith of the observer approaches that pole.

5 did exist -- only a planet in an almost polar orbit and situated near the south celestial pole could have escaped his detection.
