Jul 28, 2021 · Polaris, known as the North Star, sits more or less directly above Earth's north pole along our planet's rotational axis. This is the imaginary line that extends through the planet and out of the north and south poles. Earth rotates around this line, like a spinning top.
Polaris is a star in the northern circumpolar constellation of Ursa Minor. It is designated α Ursae Minoris (Latinized to Alpha Ursae Minoris) and is commonly called the North Star or Pole Star.
Polaris, or commonly known as The North Star, is located almost directly above the North Celestial Pole marking the way due north. Polaris is not the brightest star in the night sky. However, it is easily located making it a reliable gauge of North for travelers without a compass.

The “North Star” is the rank rather than the name of a particular star. It describes the closest star to the Earth’s North celestial pole. The North celestial pole, in its turn, is one of the two points in the sky where the Earth’s axis of rotation intersects the celestial sphere. Thus, the North Star is a star sitting closest to the Earth’s rotati...
Official Name: Alpha Ursae Minoris, α UMiAlternative Names: Polaris, Pole Star, North StarCatalog designations: HIP 11767, HR 424, HD 8890, TYC 4628-237-1Constellation: Ursa MinorThe North Star is located in the constellation Ursa Minor. It’s not exactly at the North celestial pole, but about 0.65° away, so it actually moves a little bit. The star makes a small circle about 1.3° in diameter around the North celestial pole, though it still appears motionless to the unaided eye. The North Star always points due north, but dep...
Over the course of a night, Polaris moves less than any other visible star in the sky. The main reason is that it’s almost aligned with the Earth’s rotational axis. As the Earth rotates, the North Star appears motionless, like the tip of a spinning top, and the other celestial objects seem to move around it throughout the day. But, like a spinning ...
Where is north?
Once you’ve found the North Star in the sky, you’ll find it easier to navigate on the Earth. The star always points due true north. So, face the North Star and extend your arms sideways: 1. North is in front of you. 2. Your right hand is pointing east. 3. Your left hand is pointing west. 4. South is behind you.
Best way to locate north in the Northern Hemisphere
The North Star works better than a magnetic compass for finding the true north. While a compass tells you where magnetic north is, the North Star points due true north, so you don't have to deal with the magnetic declination, which can vary from place to place. Also, a compass errs because of local magnetic influences, and the North Star always points about the same direction. It’s only 0.65 degrees away from the North celestial pole.
What is the altitude of Polaris above the northern horizon for the observer?
You can use the North Star to find out how far away north from the Equator you are right now, which is your current latitude. It was essential for navigation in the sea or deserts in the past, but even now, it may be fun to learn. The height of Polaris in the sky (its altitude) corresponds to the latitude at which you are located. If you see Polaris right above your head, at the zenith— you are lucky to be in the center of the North Pole, and your latitude is 90°. The closer you get to the Eq...

Alpha Ursae Minoris is the North Star in the sky of the modern age. It doesn’t seem to move because it’s right above the Earth’s axis of rotation, but in fact, it moves slowly across the sky, just over hundreds of years. In the year 4000, its place will be taken by the star Errai. Until then, we can use Polaris to navigate in the Northern Hemispher...
