the degree of polaris on the horizon is your latitude. Shows the curvature of the earth. When the degree of polaris is 1 degree greater, you move the some distance if you move another degree. Shows how everything is equally distant from the center.
15 degrees per hour.
42° if you round to the nearest degree
Polaris (or the North Star) is almost directly above the North pole. This means that when you stand on the north pole and look directly up, you will see Polaris. This also means that when you stand at the equator and look directly north, you will see Polaris on the horizon. You can not see Polaris from the Southern Hemisphere. The angle Polaris is above the horizon is equal to the degree latitude that you are standing on. Therefore at the equator, Polaris is 0 degrees above the horizon and at the north pole, Polaris is 90 degrees above the horizon.
They are very nearly equal angles, within about 1/3 degree. (Note the accurate implication that Polaris is not visible from anywhere in the southern hemisphere.)
If the altitude of Polaris is 43 degrees above the northern horizon, then the observer is located somewhere within roughly 1/2 degree of 43 degrees north latitude.
Polaris is within 1/2 of one degree of the North Celestial Pole. If Hattiesburg, MS is at 31 degrees north, then the elevation of Polaris is about 59 degrees - ALL the time. Within 1/2 degree, at any rate.
There are a couple of reasons that make Polaris, the north star, very useful. First of all, Polaris is not DIRECTLY above the North Pole; it's about two thirds of a degree off. But that's close enough so that if we assume that Polaris is exactly above the North Pole, you won't go very far off. So if you can see Polaris, you know which direction is north. If you measure the elevation angle above the horizon of Polaris, your reading is your latitude. No calculation is necessary!
Your latitude is 20 degrees north of the equator because Polaris is located at the celestial north pole, which is directly above the Earth's North Pole. This means that the angle between Polaris and your zenith corresponds to your angular distance north of the equator.
The North Star, also know as Polaris, is less than one degree from the sky's north pole.
Not quite. The North Star, Polaris, is about six-tenths of a degree away from being directly above the North Pole. Considering that this happened completely by chance, the coincidence is very handy.
Polaris is the star which lies within a degree of the celestial north pole, so you are facing north. It is a widely believed but incorrect idea that Polaris is very bright; it is not, but it is bright enough for you to see it on a moonless night. It is found at the end of the 'tail' of Ursa Minor, or the Little Dipper, and the Big Dipper points to it.
