An artist's concept shows the triple-star system known as Polaris, the North Star. The largest star at bottom is the one that is visible to our eyes alone.
North Star
The North Star is a title of the star best suited for navigation northwards. A candidate must be visible from Earth and circumpolar to the north celestial pole. The current one is Polaris.

The North Star is a star located close to the North Pole of the celestial sphere, i.e., the projection of the North Pole onto the sky.
NORTH STAR
The north star is a star that is located almost due north and is useful for navigation. Polaris is currently the pole star of the Northern Hemisphere.

The North Star, Polaris, is a well known star in many cultures. It is one of the navigational stars, used for orientation at sea because of its brightness and location in the sky.
The North Star Has Some Company
(Added 01/11/06) We tend to think of the North Star, Polaris, as a steady, solitary point of light that guided sailors long ago.
(a) The North Star, a second-magnitude star in the constellation Ursa Minor. The star is a yellow-white F-type supergiant that lies 330 light-years away.

Definition: star: A ball of mostly hydrogen and helium gas that shines extremely brightly. Our Sun is a star. A star is so massive that its core is extremely dense and hot.
Aligning to the North Star
Ok..Now that we have the scope balanced so that it will move in either direction freely, and stay put wherever we let go of it, it's time to "Polar Align" it.

Leading the westward moving parade are Dubhe at the lip of the Dipper's bowl and Merak, also at the bowl's front and just to the south of Dubhe, the two making the Big Dipper's "Pointers" that lead the way to the North Star.
Geographic latitude, the angle between the horizon and the North Star, Polaris. This indicates your position on the Earth, as measured from the equator.
"We sailed on night after night, the weather growing colder and colder, and the North Star climbing towards the zenith.
This really explains how the stars move pretty clearly, since they are on this spinning globe, those near the axis of the rotation, like near the North Star, would make little circles around the pole star, ...
Thus, Polaris will not always be the Pole Star or North Star. The Earth's rotation axis happens to be pointing almost exactly at Polaris now, but in 13, ...
You'll learn how to find the "North Star" and use it to figure out which way is north, your latitude and how much time has passed.
To find M81, first you need to find the north star. Now, imagine a line running from the north star, directly down to the northern horizon.
The most famous star in Ursa Minor is Polaris, the North Star. This is the star that is nearest to the North Celestial Pole. If you stood at the north pole, Polaris would be almost directly overhead.
the North Star was a star called Thuban (also known as Alpha Draconis), and in about 13,000 years from now the precession of the rotation axis will mean that the bright star Vega will be the North Star.
If you draw an imaginary line from Merak through Dubhe out of the cup of the dipper (see the picture above) and continue five times as far as Dubhe is from Merak, you will arrive at Polaris, the North Star.
The axis of Mars does not point toward Polaris, our North Star, but is displaced about 40° towards Alpha Cygni.
Find the star Polaris, also known as the North Star, in the evening sky. Identify any separate pattern of stars in the same general vicinity of the sky. Wait several hours, at least until after midnight, and then locate Polaris again.
The end star at the handle of the dipper is Polaris, the north star.
Viewing Polaris will always let you know which way is north. At the north celestial pole, Polaris will be almost directly overhead so it's also known as the Pole star.
Also, consider having the north star in the photograph. Comets are very interesting in star trail photographs showing up as fuzzy stars that move notably across the sky - while all the other celestial bodies make clean circles the comet may move ...
When Polaris will be the north star again around 27800 AD, due to its proper motion it will be farther away from the pole then than it is now, while in 23600 BC it came closer to the pole.
Polaris
The star nearest the north celestial pole, also known as the North Star. It is a common misconception that the North Star is the brightest in the sky.
In about 14,000 AD, Vega will become the North Star, owing to the precession of the equinoxes. See Polaris for more information.

For an HA-DEC antenna, the keyhole is large and, in the northern hemisphere, is centered near the North Star. To track through that area the antenna would have to whip around prohibitively fast in hour angle.
Within the constellation of Ursa Minor can be found the North Star, Polaris. By following a line from the two stars in the end of the bowl of the Big Dipper, Polaris can easily be found.

A direction determined by the projection of the Earth's North Pole onto the celestial sphere. It corresponds to a declination of +90 degrees. The North Star, Polaris, sits roughly at the NCP.

Ursa Minor (the Little Bear) is intimately linked to Polaris, the North Star which may be found at the end of the trail of stars that look like the Little Dipper.
A star that never sets but always stays above the horizon. This depends on the location of the observer. The further South you go the fewer stars will be circumpolar. Polaris, the North Star, is circumpolar in most of the northern hemisphere.
Fortunately, for those in the northern hemisphere, there is a fairly bright star real close to the North Celestial Pole (Polaris or the North star).

"Star hop" by starting with a point you can identify, like the north star. Locate it by eye, find it with the binoculars, and then, by using it as a reference point, move on to the next object.
