What constellation has the brightest stars?

The following is the introduction of Polaris. In the northern hemisphere, Polaris is undoubtedly the most important star to indicate the direction. On the starry background, Polaris is less than 1 from the north celestial pole, so when you find Polaris at night, you basically find the north. Polaris belongs to Ursa minor and is the brightest star (secondary star). Because all the stars in Ursa minor are dark except Polaris, we usually search for Polaris according to the Big Dipper. See figure 4. The Big Dipper is the main body of Ursa major. Shaped like a spoon, it is also called "spoon star" in China. When the connection between the two stars (Polaris) at the mouth of the barrel extends about 5 times outside the barrel, the Polaris can be found. There is no brighter star near Polaris, so it is easy to find it in this way. The world is easy to go. " When the Big Dipper rotates to a lower position or even sinks below the horizon due to the apparent motion on Sunday, you can look for the North Star according to Cassiopeia. The main body of Cassiopeia consists of five bright stars, which look like the Latin letter "W" and are often called "W" stars. The "W" star and the Big Dipper are separated from each other on both sides of the Polaris, which is very conspicuous. When the position of the Big Dipper is low, it is difficult to observe. W star is high in the sky. As shown in figure 4, Polaris can be found in front of the gap in the middle of W star, which is about twice the width of the gap. By the way, because Polaris is close to the north celestial pole, only people in the northern hemisphere can use it to judge the direction. Anywhere in the northern hemisphere, the height of Polaris is equal to the local geographical latitude. For example, Beijing is located around 40, and the height of Polaris seen in Beijing is also around 40.
