In which constellation can I find Polaris?

Polaris can be found in Ursa minor. It is only a rough statement that the earth rotates from west to east. In fact, the earth is autobiographical, and the sky area facing the earth's rotation axis is the North Pole, that is, the position of the North Pole star. Polaris is of great significance to human civilization. Almost all people on earth live in the northern hemisphere and can see the North Star. This phenomenon can be widely used in field activities and navigation activities. However, this was not the case in ancient times. At that time, Polaris was not so close to the North Pole, only in the last ten years. It's only one degree away from the North Pole now. Its Chinese name is dog Chen Yi. When it got this name, it was not in the North Pole. As for its western name, it was named Alpha Ursa minor. The autobiography of the earth is very complicated, accompanied by precession like a gyro, so the position of the North Pole is constantly changing. About 4800 years ago, Alpha Star in Draco was the Polaris at that time; It was not until around 2000 AD that Alpha Ursa minor stood in the North Pole. By the year 4000, Cepheus Gamma will become the North Star; By 14000, Vega will become the North Star. Therefore, in the long run, the position of the North Pole is constantly changing, and so is the Polaris. There are no bright clusters and galaxies in Ursa minor, but there are also astronomical phenomena worth seeing. There is a meteor shower here, which usually appears in 65438+February every year. It was caused by comet Tuttle. In its orbit, many dust fragments will be left, forming a long dust belt. When the earth passes through the dust belt, the dust will rub against the earth's atmosphere and form a meteor shower. The meteor shower in Ursa minor is rarely observed, and it is not vigorous when it appears, but several observers in Europe reported amazing phenomena on February 22nd, 1986, 1988, and similar phenomena also appeared in 2000. Watching Polaris is of great significance. The closer to the north, the higher its height. If you stand on the equator, it is just visible on the northern horizon; If you look at Polaris from a 33-degree line of sight, then your geographical latitude is about 33 degrees north latitude. So according to the position of the North Pole star, you can know your geographical latitude. Source: Youth Institute.
