Taoism believes: Beidou is dead, Nandou is born, if you can worship Beidou, you can become an immortal, and you will be removed from the dead forever. Nandou is in charge of survival, so the folk are also called "extended sushi". Worship Nandou can increase yang longevity.

The Southern Dipper is in the constellation Sagittarius and is said to be opposite the Cowherd. Because the six stars are also arranged in an irregular spoon. So similar to the Big Dipper.

Ancient Chinese legends are five sides and five buckets, Taoist classics say: East Dipper Lord Underworld, South Dipper on the Birth, West Dipper Name, North Dipper Death, Dou Dakui.

Nandou Xingjun Taoist god name. Nandou is the Dousu in the 28 houses, that is, the first house of the seven houses of Xuanwu in the north, because it is opposite to the Beidou, so it is called Nandou. The Nandou belief has been popular since ancient times.

<>With the successful flight of the last Beidou navigation satellite into space, China's Beidou global satellite navigation system has fully completed the deployment of the constellation. The name of the Beidou Navigation Satellite System comes from the famous symbol of the night sky in the North Sky - the Big Dipper. These seven bright stars are arranged in a spoon-shaped shape around the North Star, which can help us orient ourselves at night, which is why our global satellite navigation system is named after it.

So, why is the Big Dipper able to indicate the northern sky? What do they have to do with the North Star? How far is the Big Dipper from Earth? Are they in the Milky Way? How big is the Big Dipper?

There are so many stars in the sky that almost all of them are stars, including the Big Dipper, which can produce light and heat through nuclear fusion, just like the sun. Since the stars, including the Big Dipper, are outside the solar system, far from Earth, we can't feel their heat or see their true size.

The Earth revolves around the Sun at a speed of 30 kilometers per second, and the Sun carries the Earth and other solar system bodies around the center of the Milky Way at a speed of 220 kilometers per second. Although the Earth has been moving in space, the stars are extremely far away from us, and the distance caused by the Earth's movement changes very little, and the relative position of the stars in the night sky seems to have basically no change.

The position of the Big Dipper in space is just near the North Celestial Pole, and the North Star is very close to the North Celestial Pole. Therefore, no matter how the Earth revolves around the Sun, the northern end of the Earth's axis always points to the celestial region where the Big Dipper and Polaris are located, so these stars can indicate the north.

Just like the Big Dipper, Polaris is also a star and is a three-body system, with the other two companion stars invisible to the naked eye. The Big Dipper and Polaris are not directly related, but they are roughly the same, and the actual distance between them is very far, for example, the distance between the Celestial Pivot and the North Star in the Big Dipper is 545 light-years.

Similarly, the Big Dipper is not directly related to each other, and each of them belongs to its own star system. These stars are all about 100 light-years away from Earth, and they are all stars in the Milky Way. In fact, none of the stars visible to the naked eye extend beyond the confines of the Milky Way, and most of them are not more than 1,000 light-years away from Earth.

Here's a brief introduction to the Big Dipper:

Yaoguang is 104 light-years away from the Earth, and its mass, radius and luminosity are times that of the Sun, times and 594 times that of the Sun, respectively. Yaoguang is a very young star, only 10 million years old.

Kaiyang or Wuqu <>

Kaiyang is 83 light-years away from the Earth, and its mass, radius, and luminosity are times that of the Sun, and its radius, and luminosity, respectively, are times that of the Sun. Next to Kaiyang is a companion star visible to the naked eye, which can be seen by those with better eyesight. According to astronomical telescope analysis, Kaiyang actually belongs to a system of six stars.

Yuheng or Lian Zhen Yuheng is 83 light-years away from the earth, and its mass, radius and luminosity are times that of the sun, times and 102 times that of the sun, respectively. Yuheng belongs to a binary star system, and its companion star is a brown dwarf.

Tianquan or Wenqu <>

Yes, is an integral part of the constellation Ursa Major. The position of the Big Dipper in the constellation Ursa Major.

No. Although the Big Dipper seems to have a relatively regular brightness and an orientation that is always as far away as the North Pole, these seven stars are in different constellations, some are very far away from the Earth, and some are relatively close to the Earth.

The Big Dipper is made up of seven stars that resemble a bucket shape, all of which come from the constellation Ursa Major and can be seen year-round in the Northern Hemisphere.

The Big Dipper is composed of the seven stars of Tianshu, Tianxuan, Tianji, Tianquan, Yuheng, Kaiyang, and Shaoguang. The ancient Han people associated these seven stars and imagined them as the bucket shape of scooping wine in ancient times.

Tianshu, Tianxuan, Tianji, and Tianquan are composed of a fighting body, which is called Kui in ancient times;

Yuheng, Kaiyang, and shaking light are composed of bucket handles, which are said to be ladles in ancient times.

The Big Dipper appears in different directions in the sky at different times in different seasons and nights, so the ancients decided the season according to the direction pointed by the bucket handle at the beginning of dusk: the bucket handle points to the east, and the world is spring; Bucket handle guide, the world is summer; The bucket handle points to the west, and the world is autumn; The bucket handle points to the north, and the world is winter.

The Big Dipper starts from the top of the bucket body and ends at the end of the bucket handle, and is named in order, Ancient Chinese Han astronomers called them respectively: 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.

Taoism calls the Big Dipper the Seven Elements of the Big Dipper as the Seven Yuan Jie Xingjun, who lives in the Seven Palaces of the Big Dipper, namely: Tianshu Palace Greedy Wolf Xingjun, Tianxuan Palace Jumen Xingjun, Tianji Palace Lucun Xingjun, Tianquan Palace Wenqu Xingjun, Yuheng Palace Lianzhen Xingjun, Kaiyang Palace Wuqu Xingjun, and Shaoguang Palace Pojun Xingjun.

The Big Dipper is known as the Spoon Star.

Beidou is composed of the seven stars of Tianshu, Tianxuan, Tianji, Tianquan, Yuheng, Kaiyang, and Shaoguang. The ancients associated these seven stars with the image of a bucket shape for scooping wine in ancient times. Tianshu, Tianxuan, Tianji, and Tianquan are composed of a bucket body, and Yuheng, Kaiyang, and Shaoguang are composed of a bucket handle, which is called a ladle in ancient times.
