Summarize this article in one sentence.
Polaris is the brightest star in the constellation Ursa Minor, the Little Bear. It can be found in the bear's tail. (The ancient Greeks, and many other peoples, saw bears as having long tails.) The star is called Polaris because it appears within a degree of the Celestial North Pole and so appears not to move in the night sky. Today, because the seven stars of Ursa Minor look like a small water dipper, most people refer to Ursa Minor as the Little Dipper instead of the Little Bear. Although Polaris is visible in the northern sky at most locations north of the equator, it can be hard to spot if you don't know exactly what you're looking for. You can use stars in other constellations to point the way to Polaris. The most commonly used pointer stars are Merak and Dubhe, the two stars on the edge of the Big Dipper opposite its handle. By following these stars in the direction of the Big Dipper's mouth, you can find Polaris. If you go five times the Merak-Dubhe distance away from Dubhe you will be within three degrees of Polaris. If Polaris is clouded over, you still know where it is. During the times of night when the Big Dipper is below the horizon, such as the early hours of fall, you can use another method. Find the Great Square of Pegasus. Measure the distance from Alpheratz (visually a part of Pegasus but actually part of the constellation Andromeda), to Caph, the star at the rightmost edge of the W-shaped constellation Cassiopeia. In line with Alpheratz and Caph, measure another of these distances. You will be less than three degrees from Polaris. And, like the previous method, you do not need to see Polaris.
Look for Polaris, the North Star. Use pointer stars to help you find the North Star.
