The Big Dipper has several stars

What we call the Big Dipper refers to the 7 stars, and the star you are talking about is the companion star of Kaiyang, and these two stars constitute a binary star system, but Kaiyang is much brighter.

Which galaxy you say? Of course, it's the Milky Way, I think you want to ask which constellation it belongs to, it's the same as the Big Dipper, it belongs to Ursa Major, and of course there are many other stars in Ursa Major!

It is the companion star "Fu" next to "Kaiyang" (Ursa Major), which was used by the army in ancient times to test the eyesight of soldiers, and it has been used by Chinese and foreign armies. This star is not included in the Big Dipper.

It is "Kaiyang", which is the second star on the handle of the Big Dipper. When the weather is clear, you can see with the naked eye that there is a fainter star next to it, called the 80 stars of Ursa Major, which was called "auxiliary" in ancient China. Ancient Arab armies used it to test the eyesight of their soldiers.

The Big Dipper is, of course, those seven, and nothing else.

It belongs to the constellation Ursa Major and is numbered 80, so it is called the 80 star of Ursa Major. As for the galaxy to which it belongs, of course, the stars we can see belong to the Milky Way.

There are seven Big Dipper stars, and the Chinese names are: Tianxuan Tianji Tianshu Tianquan.

Yuheng shakes the light and opens the sun.

Careful observation shows that Kaiyang is a double star, two stars next to each other, the Big Dipper only includes the main star of Kaiyang double star when there are seven, if you count the child star there are eight (generally not counted).

..General ......

The ones that are not very bright are basically ignored.

The one you're talking about should be Kaiyang's companion star.

A constellation can be seen as a range, and all stars within the range of the Big Dipper can be seen as Ursa Major.

The Big Dipper is the constellation Ursa Major, and if it does not have that star on the constellation chart, it should not belong to the Big Dipper.

Kaiyang, which does not belong to the Big Dipper, belongs to the constellation Ursa Major.

From the bucket ladle to the bucket handle copy are: Tianshu, Tianxuan, Bai Tianji, Tianquan, Yuheng, Kaidu Yang, Shake the light below there are.

Zhi Guan Big Dipper and North.

Introducing DAO Polestar.

Polaris is now in the sky very close to the Earth's North Pole. Therefore, it looks like it is always in the northern sky. It is precisely because of its important location that it is famous.

In fact, according to its brightness, it is just an ordinary second-magnitude star, which belongs to the "small characters". It's more than 300 light-years away. Polaris belongs to the brightest star in the constellation Ursa Minor, also known as Ursa Minor.

In ancient China, it was called "Gou Chen Yi" or "Beichen". On the constellation graphic, it is at the tip of the bear's tail.

8 fine stars, the fourth star is a double star, but it is relatively faint and not easy to see.

Seven, haven't you heard of the Big Dipper.

By standard, there are more than 20, including many Gemini stars and a star cluster.

As of July 2020, there are 55 Beidou navigation satellites.

There are three generations of Beidou system development so far, of which the first generation is also known as the "Beidou Satellite Navigation Test System", which is an experimental nature, and the Beidou system since the second generation is officially called the "Beidou Satellite Navigation System".

1. The Beidou-1 system (the first generation of the Beidou system) provides regional positioning services by three satellites. Since 2000, the system has been providing navigation services mainly within China. In December 2012, the last satellite of Beidou-1 expired, and the Beidou Satellite Navigation Test System ceased to operate.

2. The Beidou-2 system (the second-generation Beidou system) is a global satellite navigation system containing 16 satellites, including 6 geostationary orbit satellites, 6 inclined geosynchronous orbit satellites, and 4 medium earth orbit satellites. In November 2012, the second-generation Beidou system began to provide users with regional positioning services in the Asia-Pacific region.

3. The Beidou-3 system (the third-generation Beidou system) consists of three satellites with different orbits, including 24 satellites in the Earth's medium circle orbit (covering the whole world), 3 satellites in inclined geosynchronous orbit (covering most of the Asia-Pacific region) and 3 satellites in geostationary orbit (covering China).

In 2018, BDS-3 opened the global positioning function of the Beidou system ahead of schedule. On June 23, 2020, the last global networking satellite of Beidou-3 successfully entered the scheduled orbit, and the launch mission was a complete success.

The Big Dipper is the Big Dipper. The Big Dipper is composed of Tianshu, Tianquan, Tianji, Tianxuan, Yuheng, Kaiyang, and Shaoguang. One of the hallmarks of the Northern Hemisphere starry sky, these seven stars look brighter and look like spoons.

And along the direction of the spoon's opening, it is also easy to find the North Star, which can be identified at night.

Astrological Signs: The Big Dipper is an important star in the sky of the Northern Hemisphere, composed of seven stars: Tianshu, Tianxuan, Tianji, Tianquan, Yuheng, Kaiyang, and Shaoguang (also known as Yaoguang). The Big Dipper is a star official belonging to Ziweiyuan.

The Book of Jin and the Astronomical Chronicles record that the pivot is the sky, the Xuan is the earth, the Ji is the person, the right is the time, the balance is the sound, the sun is the law, and the light is the star. Among the seven stars, "Yuheng" is the brightest, and its brightness is almost close to that of a first-magnitude star. "Tianquan" is the darkest and is a third-magnitude star.

The other five are all second-magnitude stars. There is a very small companion star near "Kaiyang", called "Kaiyangfu" or "Kaiyang Zengyi".

Answer: The Beidou system has a total of 35 satellites. The space segment of the Beidou Navigation Satellite System consists of 5 geostationary orbit satellites and 30 non-geostationary orbit satellites.

At an altitude of more than 20,000 kilometers above the ground, 35 satellites orbit the earth in a fixed period, so that more than four satellites can be observed at any time and at any point on the ground. <>

How many Beidou satellites are there?

Answer: The Beidou system has a total of 35 satellites. The space segment of the Beidou Navigation Satellite System consists of 5 geostationary orbit satellites and 30 non-geostationary orbit satellites.

The 35 satellites orbit the earth at a fixed period at an altitude of more than 20,000 kilometers above the ground, so that more than four satellites can be observed at any point on the ground at any time and at the same time. <>

The role of satellites: 1. Artificial earth satellites operate in their respective orbits, but their functions and uses are different, and they can be roughly divided into five categories: communications, meteorology, resource rubber, reconnaissance, and navigation. 2. Communication satellites.

Its function is to transmit TV and ** signals for people. Without it, it's hard to play across the ocean ** or ** world news, international competitions. 3. Meteorological satellites.

It carries remote sensing equipment that looks down on the entire Earth's atmosphere and monitors winds, clouds, rain and forest fires on Earth. The images and data recovered by meteorological satellites are the basis for meteorological scientists and technicians to accurately forecast the global weather. 4. Earth Resources Satellite.

It uses remote sensing instruments to discover geographical features that are difficult to find on the ground and at low altitudes, and uses the information it obtains to accurately estimate the resources of vegetation, geology, water, and sea water in various regions of the earth. 5. Reconnaissance satellites. It is equipped with high-resolution cameras and video cameras to photograph ground targets, which can accurately reflect the movement and build-up of ground forces and the changes in various military installations.

6. Navigation satellites. Helping ships at sea to find their direction and position. Through the observation and ranging of more than two satellites, the ship knows exactly the coordinates of its geographical location.

What is the name of the brightest star around the Big Dipper.

It's a celestial star. In the northern sky, there are seven bright stars arranged in the shape of a bucket (dipper). We often call them the Big Dipper.

The names of these seven bright stars are: Tianshu, Tianxuan, Tianji, Tianquan, Yuheng, Kaiyang, and Shaoguang.

The Big Dipper Seven Stars are the seven star gods worshiped by Taoism, that is, the "Big Dipper". But in Chinese culture, the worship of the stars, including the Big Dipper, has a long history, long before Taoism was formed. The Confucian celebration system also emphasizes the sacrifice of the stars.

China is one of the earliest countries in the world in the development of astronomy, and the observation of the Big Dipper has long been recorded, but the most complete record of the names of the seven stars was first found in the Weishu of the Han Dynasty.

Originally, there were two names for the cover, one was recorded in the "Spring and Autumn Fortune Doushu". He said: "The first day pivot, the second rotation, the third Xuan, the fourth power, the fifth balance, the sixth opening of the sun, and the seventh shaking light." The first to fourth are the kui, the fifth to the seventh are the standard, and the fight is the fight. ”

In addition, the Kui Star worshiped by students throughout the ages, that is, the first star (or the first four stars) of the Big Dipper, it is said that the Kui Star is the Wenqu Star, but there is no doubt that the Wenqu Star and the Kui Star are in the first four stars of the Big Dipper.

Taoism calls the Big Dipper the Seven Stars as the Seven Yuan Relief 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 Wuqu Xingjun, Yaoguang Palace Pojun Xingjun.
