How to find the Big Dipper, the location of the Big Dipper, how is it determined?

Before you can make an observation, you need to determine the latitude of the place where you are observing. Because the horizon height of the North Star is equal to the geographic latitude of the observer.

After determining the latitude, when the sunny night falls, you face due north, your eyes are horizontal, your head is raised, and the angle is the degree of the latitude you just determined (if you are at 45 degrees north latitude, then you will raise 45 degrees, how to measure this angle, hehe, simply find a protractor to make it). At this time, there should be a star in the center of your field of vision that is brighter than the surrounding stars, this star is called Ursa Minor, and the traditional name in our country is "Gou Chen Er". It is also commonly known as the North Star (the North Pole of the sky is the direction of the Earth's axis, in fact, this star is not the location of the real North Pole of the sky, but it is currently the bright star closest to the North Pole of the sky.

Due to the "precession", after 12,000 years, Vega will become the North Star). Polaris never sets, and you can see it during the day if there is a total solar eclipse. Another thing to understand is that in the Northern Hemisphere, when you look at the starry sky, all the stars revolve around the North Star (think for yourself why?). , which is why the North Pole is located first when using astronomical telescopes.

Let's talk about the Big Dipper. The Big Dipper consists of seven stars and is part of the constellation Ursa Major in modern astronomy. In fact, these seven stars are relatively easy to recognize in the northern sky, the four stars of the bucket spoon are close to the direction of the North Pole, and the bucket handle is three stars outside.

Most people find the Big Dipper first and then the North Star when they don't have tools. As mentioned earlier, the Northern Hemisphere star rotates clockwise around the celestial north pole, so when you observe the Big Dipper at different times, its position will be different. There is an old Chinese saying that can be remembered:

The bucket handle refers to the east, and the world is spring; The bucket handle refers to the south, and the world is summer; The bucket handle refers to the west, and the world is autumn; The north finger of the bucket handle, the world is winter. In other words, at dusk in the spring night, you can see the handle pointing east, and so on. At this point, you can find the spoon in the direction of the handle.

If you're at a high enough latitude, you'll be able to see it all night long (although there may be a time when the Big Dipper is above you).

Frequent observation can increase experience, and it is not interesting to talk on paper, so let's go out quickly.

Depending on the season, the position of the Big Dipper is also different. The bucket handle points to the east, and the world receives spring; The bucket handle refers to the south, and the world is summer; The bucket handle refers to the west, and the world is autumn; The north finger of the bucket handle, the world is winter.

From Tianxuan to Tianshu (that is, the first and second stars of the spoon head) extend a straight line outward, extending the distance by a factor of 5, and there is a star as bright as the Big Dipper, which is the North Star. The direction of Polaris is due north.

You can find the North Star first, and then follow the above method to reverse the Big Dipper to find the Big Dipper

In the evening, when the weather is good, look north, and the 7 stars are arranged like spoons.

If you find Tiangang Star, you will find the Big Dipper.

Introduction: Our country also has its own navigation system, which is our Beidou navigation system. You know the Big Dipper.

How was the location determined? Let's find out.

We will know that the Big Dipper is the Big Dipper in our sky, it is the brightest combination of red stars you see at night, and the Big Dipper can help us find our way to the North Star.

So we don't lose our way, but find where we want to go and find our way home.

The Beidou navigation system is a very good navigation system, and it is a great progress in science and technology for China. In fact, the position of the Big Dipper is determined by some stars connected together, so we found the Big Dipper.

You can reconnect some of them, and then we will see a relatively large red heart, which is called Polaris.

At night, we can recognize the way home and the direction. The Big Dipper also has his own name, the seven stars that make up the Big Dipper, their names are Tianshu Xingtian Xuanxing Tianji Xingyu Stellar Heaven, Quanxing Xingxing, Yang Xing and Yaoguang.

Yes. His names are very nice, and they will have their own shape in the sky, like a sock branch to a small spoon, so they are all different from the earth, so their size is also to be distinguished.

And when we look at these stars on Earth, the Big Dipper revolves around a star, Polaris, so people will have a rule to summarize that we know that the Big Dipper only changes the beginning of the four seasons of the year on Earth. So whether it's spring, summer, autumn or winter.

In any season, the Big Dipper, its position in the sky is near the North Star, and its Doukou Tianshu Star and some space-based lines will always be with the North Star, and the only thing that changes to the North Star is some drugs, because they will point in different directions with the change of the season.

As the name suggests, it is composed of seven stars in the north of the sky, and the shape is like a bucket (spoon) for scooping wine. Knowing the meaning of the name, I only need to look for a set of stars shaped like spoons in the north of the sky to find the Big Dipper.

The location of the Big Dipper is due north, and you can find the Big Dipper when you see due north.

Depending on the season at the time, the Big Dipper does not appear in every season, and the Big Dipper is in the shape of a spoon.

You can find the North Star, and then find the Big Dipper according to the North Star, you can find the location very well, and you can judge it very well.

Determined by the seasons, we can find the Big Dipper, which is shaped like a spoon.

SeekingNorth StarThe way to do this is to look for it firstThe Big Dipper, from the mouth of the Big Dipper (ieTianshuand Tianxuan) direction, extend it 5 times upwards to find the North Star.

The Big Dipper is one of the seven bright stars in the constellation Ursa Major and is shaped like a spoon and is used to distinguish other stars because they are easy to identify. When you are in the northern hemisphere, as long as you find the Big Dipper, you can find the North Star, which is fixed at the North Pole for a long time, so it is used as an indicator to identify the north.

Chronicles

Big dipper. The rotation corresponds to the observation of one day, one month, and one year on the earth, and the space is divided into 12 houses, such as Zi, Chou, Yin, and Mao, with the center of the North Celestial Pole.

The Big Dipper revolves around it, and its monthly, daily, and hourly celestial phenomena, such as the hour hand, minute hand, and second hand of the clock, rotate regularly, and the solar is known for daily, yearly, moon daily, and monthly periodic changes of the celestial phenomena also have the role of a clock calendar.

Through the regularity and cycle of the sun, moon, and the Big Dipper, the ancients abstracted the calendar of the ten heavenly stems and twelve earthly branches.

The Big Dipper is located in the constellation Ursa Major.

The Big Dipper is centered on the North Star, and the bucket handle rotates counterclockwise, extending the connection of the two stars on the side of the Big Dipper, and at about 5 times the distance between the two stars, there is a brighter star, 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 Beichang or Fang 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 very spectacular, and the two stars at the mouth of the spoon are extended by five times, and the North Star can also be found.

The Big Dipper is located in the constellation Ursa Major.

Big dipper. Seven stars to the North Star.

As the center, the bucket handle rotates counterclockwise, extending the line between the two stars on the spoon side of the Big Dipper, and at about 5 times the distance between the two stars, there is a star that is brighter than Han's, which is the famous North Star. In the spring, the west wind points to the east, the summer bucket handle guide is opened early, 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, which is the famous Big Dipper, which is easy to see with the naked eye, because the Big Dipper is spectacular, and there will be two stars in the spoon mouth.

and the Celestial Spiral are extended five times, and the North Star can also be found.

The Big Dipper in winter is northeast of the sky, with the handle pointing north. In summer, the Big Dipper is northwest of the sky, and the handle is pointing south. 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.

Differences: The seven stars in the constellation Ursa Minor in Songqing Hall are called Little Beidou; The emperor star is in the constellation Ursa Minor, and the Beidou is in the constellation Ursa Major, and the so-called bucket is the emperor's car.

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 astronomers called them 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.

Part of the constellation Ursa Major, the Big Dipper is graphically 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." "Beginners can come to the other constellations from the Big Dipper.

2. The Big Dipper starts from the upper end of the bucket body to the end of the bucket handle, and is named in order.
