The point in the sky directly above the north or south pole of the Earth.
either of the two points projected onto the celestial sphere by the extension of the Earth's axis of rotation to infinity.
Points above the Earth's north and south poles.
extension of Earth's axis of rotation on the sky (celestial sphere).
one of two points of intersection of the Earth's axis and the celestial sphere
one of the two points on the celestial sphere around which the diurnal rotation of the stars appears to take place.
Either of two diametrically opposite points at which the extensions of the earth's axis intersect the celestial sphere ... north to a point about 1û from Alpha Ursa Minoris (Polaris), and south to a point about 1û from Sigma Octantis (a fairly dim star sometimes called Polaris Australe). Often referred to as the north pole or south pole. The tilt of the Earth's axis causes the celestial pole above our planetary pole to describe a great circle in the sky over long periods of time. In 4500 BCE, Thuban, a star in the tail of Draco, marked the celestial north pole. This pole has, over time, shifted to Polaris and in about 12,000 years will shift to Vega
One of the two points in the sky around which the celestial sphere seems to rotate.
These are simply the projections of the Earth's poles, onto the celestial sphere. The declinations of the North and South celestial poles are 90°N and 90°S respectively. The star Polaris is very close to the North celestial pole. The poles provide an easy way of measuring latitude. Simply, the angle between the pole and the horizon, in degrees, is the equivalent to your latitude. See also celestial equator.
the imaginary projection of Earth’s rotational axis onto the celestial sphere
The projection of Earth's rotation axis poles onto the sky. In the northern hemisphere, the celestial pole is within a degree of Polaris, the North Star.
One of the two points on the celestial sphere directly above Earth's poles.
The two celestial poles are the imaginary points where the Earth's spin axis intersects the imaginary rotating sphere of stars called the celestial sphere.
