Not included! The Big Dipper is part of the constellation Ursa Major, and graphically, the Big Dipper is located on the back and tail of the Ursa Major. Six of these seven stars are of 2nd magnitude and one is of 3rd magnitude.
Through the connection of the two stars in the bucket mouth, it is extended about 5 times in the direction of the bucket mouth, and the North Star is found. The song of recognizing the stars has: "Recognizing the stars first comes from Beidou, and then from the north to the west."
The Big Dipper starts from the top of the bucket body to the end of the bucket handle, and is named in order, In ancient China, they were called: Tianshu, Tianxuan, Tianji, Tianquan, Yuheng, Kaiyang, and Shaoguang. From the "Tianxuan" through the "Tianshu" outward a straight line, about 5 times longer, you can see a star as bright as the Big Dipper, which is the North Star.

First of all, you have to know the direction, know that the north is in **, and then it is actually very easy to recognize. In spring, it is easier to see the Big Dipper in April and May, in fact, you can see it in all seasons, but I don't know where you live, and in April and May, around eight o'clock in the evening, the Big Dipper rises back to a place in the sky where it is easier to see, and the brightness of the surrounding planets cannot be compared with the Big Dipper. Once you find them, you can follow the two stars at the front of the spoon and extend the distance in the direction of the top of the spoon by about five times, and another bright star but not as bright as the Big Dipper, which is the North Star.

Relationship between the position of the Big Dipper and the North Star: The North Star is on the five-fold extension of the line between the Celestial Xuan Star and the Celestial Pivot Star in the Big Dipper.
The Big Dipper is the main star of Ursa Major, and Polaris is located near the North Celestial Pole and is the main star of Ursa Minor, and the differences between the two are as follows: 1. The number of the two is different; 2. The roles of the two are different; 3. The position of the two is different.
1. The number of the two is different: the Big Dipper is made up of seven stars, while the North Star is one star.
2. The role of the two is different: the role of the Big Dipper is to help people find the location of the North Star, while the role of the North Star is to help people identify the direction of due north.
3. The two are in different positions: the Big Dipper is located at the tail of the constellation Ursa Major, while the North Star is on the five-fold extension of the line between the Celestial Xuan and the Celestial Pivot.

There are two reasons for this:
1. Light damage and haze are too serious.
2. The season is wrong. The Big Dipper is most pronounced in spring, followed by summer. Spring from March to May is the best time to see Beidou, when they appear in the northern sky at night, and the position is relatively high.
Big Dipper: The Big Dipper is centered on the North Star, and the bucket handle rotates counterclockwise, extending the connection of the two stars on the spoon side of the Big Dipper, and there is a brighter star at about 5 times the distance between the two stars, which is the famous North Star.
In the spring, the west wind points to the east, the summer bucket handle guide, and in the autumn, the Milky Way comes to the west, and the Big Dipper is on the northern horizon. You may not be able to see it because there are tall buildings or trees. In winter, the Big Dipper is in the northeast.
The Big Dipper is visible in the north after dusk, and you can see a spoon-shaped 7 planets, that is the famous Big Dipper, which is easy to see with the naked eye, because the Big Dipper is spectacular, extending the two stars of the spoon mouth Tianshu and Tianxuan by five times, and the North Star can also be found.

The North Star is on the extension line of the Big Dipper.
Throughout the year, the pointing of the handle of the Big Dipper changes with the seasons, but the relative positions of the Big Dipper and the North Star are constant.
The Big Dipper is part of the constellation Ursa Major and is located at the tail of Ursa Major, and its orientation is difficult to determine, because in different seasons, the Big Dipper will be located in different directions, and these things are recorded in many ancient books, such as "The bucket handle points to the east, and the world is spring; Generally speaking, it is located in the north, and many people are waiting for the time when they get lost in the wild, and they all rely on the Big Dipper to distinguish the direction.
Related introductions. The Big Dipper is located 78 light-years to 124 light-years from Earth, and is part of the constellation Ursa Major.
The Big Dipper and Polaris are not far apart, and once you find Polaris accurately, the Big Dipper will appear near it, because the two are interdependent in the sky.
The connection between Tianxuan and Wu Xintianshu of the Big Dipper points to the North Star, and the North Star barely changes position in the sky.
Due to the rotation of the Earth, the position of the Big Dipper changes with the four seasons of spring, summer, autumn and winter as seen from the Earth.

The relationship between the North Star and the Big Dipper is that the Big Dipper rotates counterclockwise with the North Star as the center.
Polaris is positioned very close to the extension of the Earth's axis of rotation, so no matter how the Earth rotates, Polaris will not rotate, but will move slowly near the North Celestial Pole. The Big Dipper is farther away from the North Celestial Pole, and as the Earth rotates, we will see the Big Dipper rotating around Polaris in a counterclockwise direction on Earth, because the Earth's rotation is counterclockwise when viewed from the North Celestial direction.

First of all, please find the Big Dipper.
Follow the opposite direction of the handle to find the two stars behind the bucket body. Then, imagine connecting the two stars in a straight line.
Then, extend this imaginary straight line five times more--- there is a medium-bright star. In that sparsely stard area, the star that shines alone is the North Star.
The position of the North Star is vertically looked down and seen by the horizon.
The direction is the north.

The Big Dipper and Polaris are constellations that we often hear about in our daily lives. Their position in the sky has always been one of the focuses of research. The Big Dipper refers to a group of bright stars, arranged in a spoon shape, the brightest of which is the Big Dipper.
Polaris is a bright star located above the North Pole.
The positions of the Big Dipper and the North Star are closely related. The North Star is located at the North Pole and slightly off-center, while the Big Dipper is located in the Big Dipper position. If we can find the Big Dipper, we can find the North Star, because the North Star is located on the pointing line of the Big Dipper.
The four longer stalks of the Big Dipper point to the position of the North Star. This is also the important position of the Big Dipper in the ancient Chinese calendar.
In navigation and constellation observation, both the Big Dipper and the North Star play an important role. The North Star is widely used in navigation because it is located almost at the northern end of the sky and can be conveniently used to help navigators determine their direction as clear as possible. For stargazers, the Big Dipper is a great place to start and help people find other constellations.
In general, the Big Dipper and Polaris have a relatively fixed position in the sky, and they have the function of guiding the direction and finding constellations, which are deeply loved and valued by the public.
The Big Dipper is composed of seven bright stars in the constellation Ursa Major, arranged in a bucket (or spoon) shape in the northern sky, and is often used as an important symbol to indicate direction and understand the constellations. Because these seven stars are easily recognizable to stargazers, they become a distinct and important constellation. >>>More
