The legend of the North Star, which one does the North Star refer to

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).At this time, there should be a star in the center of your field of vision that is brighter than the stars around it, this star is called Ursa Minor, and the traditional name of 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 pointing to the Earth, in fact, this star is not in the position 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 of shadowing, 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 bucket spoon in the direction of the infiltration and faction of the bucket 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 your head).

Frequent observation can increase experience, so let's go out quickly.

1. 8-9 p.m. In the northern sky of China, looking up at an angle of 45°, it is found in the easterly sky'w'There are seven stars in the shape of a 'spoon' in a straight line to the southwest, and between the two constellations, the brightest star is the North Star.

2. Polaris is located in the constellation Ursa Minor, about 400 light-years away from the Earth, and is a bright and stable star that can be seen in the night sky. Polaris is now in the sky very close to the Earth's North Pole. You can find the Big Dipper by looking for dust first, and find the North Star through the Big Dipper.

One of the Big Dipper signs of the Big Dipper, the Big Dipper, graphically, is located on the back and tail of the Big Bear. 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 from Beidou, from north to west." "Beginners can find other constellations from the Big Dipper.

From the perspective of love, the North Star symbolizes steadfastness, perseverance and eternal protection. If it is anthropomorphized, then it must have a commitment to the star that is close to it, otherwise it will not be protected without abandonment, such as the moon, although they are far away, but the North Star still guards. So the North Star is very firm and symbolizes that it will never change.

Polaris once said to Earth, if you get lost at any time, look up at me, and I will always be here for you. So people who get lost will look up to look for the North Star. Because the position of the North Star is relatively stable and not easy to change, it gives the impression of loyalty and has its own position.

From a life perspective, the North Star has the meaning of guiding us to our goal, just as it allows us to discern directions.

In Chinese tradition, the North Star has extraordinary significance, the ancients will be the Beidou and the pole star as a whole to understand, called "Douji", the pole is in the center of the rotation of the starry sky, the stars rotate around it, as if the sky dominates, and the ancients to the Beidou dipper around the four fingers to determine the season, Beidou has become the maker of the order of heaven and earth, spring and summer, autumn harvest and winter collection seem to be coming with the Beidou point.

The North Star is a very important indicator of field activities and ancient navigation directions, and it is also a constellation that can identify the direction of stargazing, as well as astrophotography and accurate positioning of the equatorial mount in the observation room. Due to the closest aspect of the North Star to true north, people on Earth have relied on its starlight for thousands of years to navigate.

In ancient China, it was called "Gou Chen Yi" or "Beichen".

In Chinese tradition, the North Star has extraordinary significance, such as the North Star "Taiyi" in the era of the Five Emperors in 2263 BC and the North Star "Emperor" in the Zhou Dynasty in 1097 BC. This is due to the fact that they appear to be fixed in the sky and are embraced by the stars, so they are considered the lords of the stars.

Erya Shakti" contains:

The North Pole is called the North Star.

The Analects of Politics contains:

For politics and morality, such as Beichen, live in its place, and the stars arch it.

Watching the Phenomenon and Playing Occupy contains:

The North Star is in the Ziwei Palace, a North Star, the most respected star in the sky. Its new star is also the pivot of the sky. The heavens are endless, the three lights shine one after another, and the pole star does not move. Therefore, it is said: "Dwell in its place and the stars arch over it." ”

It is the one called "Gou Chen" in the picture.

On the left side of the ** there are the Big Dipper, like a handful.

Spoon. Extending the distance from the "Spoon Edge" below to the "Spoon Opening" direction (**right) is about 5 times the North Star.

Polaris refers to the star closest to the North Celestial Pole, and is located in a constellation called Ursa Minor, officially known as "Ursa Minor", which is the brightest star in the constellation Ursa Minor. It is a yellow giant with a spectral type of f, about 434 light-years from Earth, with a mass about 4 times that of the Sun, an apparent star, and so on.

Although it is not too bright, there is no brighter star near it. This star was called "Gou Chen Yi" in ancient China.
