What do the Big Dipper look like in autumn and winter?

The Big Dipper. It rotates on the axis of the North Star. In "The Crane Crown".

Huainanzi is described like this: "The bucket handle points 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. Depending on the seasons throughout the year, the handle of the Big Dipper points differently, and it rotates clockwise around the North Star.

Therefore, the Big Dipper "Bucket Handle North Finger" in winter; And in autumn, it is "the bucket handle points west".

The Big Dipper often hangs above the sky of the Northern Hemisphere and can only be observed by people in the countries of the Northern Hemisphere. Everyone knows that the shape of the Big Dipper will not move, so how does the passive Seven Stars maintain its spoon-like shape, you might as well take a look at the Big Dipper ** analysis with Discovery.com to understand the true appearance of the Big Dipper.

The Big Dipper, in the constellation Ursa Major, is made up of seven bright stars in the constellation Ursa Major. Everyone knows that the Big Dipper will not change now, it has always been spoon-shaped, but in different seasons and different times, the position of the Big Dipper in the northern sky is slightly different, and the direction of the bucket handle will also change. Depending on the season, the position of the Big Dipper in the night sky in the first half of the night is also different.

Therefore, the ancient people of our country determined the seasons according to the change of its position. "Ganshi Star Sutra":"The Big Dipper is called the Seven Politics, the princes of the sky, and the emperor car. "The emperor sat on the Big Dipper to inspect the four directions, set four hours, and divided the cold and heat.

Will the shape of the Big Dipper change?

The Big Dipper is always moving slowly in relative motion in the sky, with five of the stars moving in one direction at about the same speed, while the "Celestial Pivot" and the "Shaking Light" move in opposite directions. Therefore, in the long cosmic transition, the shape of the stalk will change greatly, and we will not see this shape of the stalk.

Since we are in the Northern Hemisphere, people in the Southern Hemisphere will not be able to see the Big Dipper. And the North Star of the Big Dipper, that is, the star on the tail, is exactly at the very north pole of the celestial sphere, and due to the rotation of the earth, the star on the tail appears to be motionless, while the rest moves clockwise around the North Star because the Earth rotates counterclockwise. Due to the difference in the angle of rotation and revolution, the position of the Big Dipper changes at the same time in different seasons, and the spoon handle points to the southeast, northwest and northwest respectively in spring, summer, autumn and winter, so the change is that the spoon handle changes from pointing east to pointing south.

The Big Dipper is sometimes in the northwest and sometimes in the northeast. Their position changes from moment to moment. Because the earth is always rotating.

The Big Dipper revolves around the North Star at all times, causing the handle to point in a different direction. All stars, including the Big Dipper, revolve around the North Star once a day, which is known as the star's Sunday apparent motion. The handle of the Big Dipper rotates like the hands of a clock, one degree in 4 minutes.

One turn in 24 hours. You can observe stars such as the Big Dipper at night, and the Sun during the day.

In the north of the night sky, the North Star corresponding to the Big Dipper is due north, and there are actually many constellations that can be seen in winter. It's just that most constellations don't have many bright stars above magnitude 2, and some even have only one. And due to the light pollution in the night sky, we can only see second-magnitude stars on the best days now.

This makes most of the constellations unrecognizable.

The position of the Big Dipper is related to two conditions: the season and the local time. It makes no sense for the landlord to discuss only one condition.

Take around 8 p.m. as an example: south of the North Star in the spring, west in the summer, north in the fall, and east in the winter. ,8,Throughout the year, the handle pointing of the Big Dipper changes with the seasons, but the relative positions of the Big Dipper and the North Star are constant.

If you are still young, you might as well observe it for yourself, this is not only a learning method, but also a life experience. , 2, due to the rotation of the Earth, the effect of the Big Dipper rotating 360 degrees around the North Star every 24 hours will be seen on Earth. For example, tonight, at 8 p.m., the Big Dipper will be "northwest" (top left) of Polaris, and at 12 o'clock, it will be "west" (left).

It can be seen that the position of the Big Dipper relative to the North Star has nothing to do with the season.

1. Spring in the East. Summer in the South. Autumn in the West, Winter in the North. The above observations are for the Northern Hemisphere only. ,1,

The spoon heart of the Big Dipper is always facing the North Star, and according to the direction of the Big Dipper changes throughout the year, the drawing steps are as follows:

1. Draw a North Star, make 4 45-degree diagonal lines around the North Star, the spoon center of the Big Dipper, pointing to the North Star, and the spoon tail pointing in the positive direction.

2. When the tail of the spoon points to the east, it is spring, and when the tail of the spoon points to the west, it is autumn.

3. When the tail of the spoon points south, it is summer, and when the tail of the spoon points north, it is winter.

There is a picture of the four seasons of the Big Dipper **, the landlord can take a look.

Hope it helps.

1.Chinese star name (hereinafter referred to as "middle name") Tianshu Beidou Yi is also called "Kui" "Kui" International star name (hereinafter referred to as "international name"): Big Bear Alpha.

3.Middle name: Tianji Beidou three international name: Big Bear Gamma.

4.Middle name: Tianquan Beidou IV International name: Big Bear Delta.

The above four are called "kui", which means that the actual kui star is four. And "Beidouyi" is the first "Kui", so it is also called "Kui", because it is the main star of "Kui", so sometimes the first is also called "Kui Star".

It's not going to change now, it's always spoon-shaped, and it will take about 100,000 years for it to change shape.

The ancients had already named it, and now foreigners are talking nonsense, China knew the Big Dipper three thousand years ago.

The Big Dipper. It is composed of the seven stars of Tianshu, Tianxuan, Tianji, Tianquan, Yuheng, Kaiyang, and Yaoguang. Ancient China.

The people connected these seven stars and imagined them as the bucket shape of the ancient Na Kaixiang Dynasty scooping wine.

The Big Dipper starts from the upper end of the bucket body and ends at the end of the bucket handle, and is named in order, early rent, δ ancient Chinese astronomers called them respectively: Tianshu, Tianxuan, Tianji, Tianquan, Yuheng, Kaiyang, and Yaoguang. 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.

The Big Dipper resembles a spoon in the north of the sky and consists of seven stars, each representing a different meaning.

Tianshu, Tianxuan, Tianji, and Tianquan are composed of a fighting body, which is called Kui in ancient times; Yuheng, Kaiyang, and Yaoguang are composed of bucket handles, which are called ladles in ancient times.

Big dipper. In different seasons and at different times at night, it appears in different directions in the sky, so the ancients decided the season according to the direction of 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; Li Bo pointed to the west, and the world was autumn; The bucket handle points to the north, and the world is winter.

The ancients observed the Big Dipper at dusk to determine the seasons: the bucket handle points to the east, and the world is spring; The bucket handle points to the north, and the world is summer; The bucket handle points to the west, and the world is autumn; Bucket handle guide, the world is winter.

By observing the direction of the handle of the Big Dipper, you can determine whether it is spring, summer, autumn or winter. In the fall, when the Big Dipper has turned to the horizon, to find the North Star, you need to find the constellation Cassiopeia with five stars opposite the Big Dipper.

The direction of the North Star is due north, and the Big Dipper moves from east to west around the North Star. When we get lost in the wilderness, we can determine where we are according to "up north, down south, left west, right east". The changes of the Big Dipper change with the seasons and time, but no matter how it changes, the direction of the North Star pointed to by the Big Dipper is unchanged, and it always points to the Earth's North Axis.

By looking at the direction of the North Star, we can determine the direction we are looking for.

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.

Spoon handle, southeast, northwest, spring, summer, autumn and winter.

Why is the Big Dipper handle pointing to Yin's position now?

Winter Big Dipper in the northern sky. The handle points north. The bucket handle refers to the east, the world is spring, the bucket handle guide, the world is summer, the bucket handle points to the west, the world is autumn.

Now the door handle points to Yin's position, what's going on?

Its position is constantly changing slowly, not constantly.

It will change slowly and continuously depending on the solar term.

It should be the first month of the year?

Now the Big Dipper should be pointing after February 4 next year.

Due to the fact that the date of the lunar calendar is fixed every year, there is a difference between the date and time of the sun, and its position is not accurate according to the lunar calendar.

Now the pointing of the Big Dipper's handle is 45 degrees different from the theory, forget what's going on?

What is the theory? Its direction of rotation rotates according to a fixed natural law and does not change suddenly.

That has changed now.

Its position is in a constant and slow change, not fixed. It's constantly turning.

<> "The Big Dipper belongs to the constellation Ursa Major, which is composed of seven bright stars in the shape of a spoon, commonly known as the spoon star, according to which it is easy to find the North Star. During the four seasons, it rotates around the North Star in a counterclockwise direction, and its position in the sky is constantly changing, but its shape does not change early or wide.
