The sun is closer at sunrise than at midday The sun is farther or closer to people at sunrise?

Just as close as we can say that at noon we are closest to the Sun and the Earth is just as close to Earth.

The sun is the same distance from the earth in the morning and at noon.

The reason for this is that the Sun is about 6,400 kilometers away from us (i.e. the radius of the Earth), but this difference is insignificant in relation to the distance between the Earth and the Sun (about 150,000,000 kilometers from the Earth), so the Sun in the morning and at noon can be said to be almost the same. Why does the sun look bigger in the morning than at noon?

It's a visual error, a mistake.

The same object, placed in a group of objects larger than it, appears small, while placed in a group of objects smaller than it appears large. In the same way, the morning sun rises from the horizon against the backdrop of trees, houses, distant mountains and a small corner of the sky, and in this comparison, the sun appears larger. At noon, when the sun rises high and the vast sky is the backdrop, the sun appears smaller.

Hyo-qin. Secondly, the white part of the same object appears larger than the black one, and this physical phenomenon is called "photoosmosis". When the sun is rising, the background is a dark and dreary sky, and the sun is exceptionally bright; At noon, the background is the blue sky of Sun Sheng, and the contrast between the sun and its brightness is not much, so it looks smaller.

Original text: Confucius traveled eastward, saw two children arguing, and asked why. Yi'er said:

I go near at the beginning of the sun, and far away in the middle of the day. "A child is far away at the beginning of the day, and the middle of the day is near. Yi'er said:

The beginning of the day is as big as the car cover, and in the middle of the day, it is like a plate, which is not small for the far and big for the near? "A son said: "Yun Crack" is cool at the beginning of the day, and it is like exploring the soup in the middle of the day, which is not hot for the near and cold for the far?

Confucius couldn't decide. The two children smiled and said: "Who is more knowing!"

The article >Two Children's Debate Day" is selected from "Liezi Tangwen", which is said to have been written by Zheng Guoren Lie Yukou during the Warring States Period. The article makes Confucius unable to judge who is right and who is wrong through the debate between two children, which shows that if you look at the problem from different angles, there will be different results, and there is no absolute right or wrong, so even Confucius cannot judge it. It illustrates Confucius's pragmatic attitude of "knowing is knowing, and not knowing is not knowing", thus reflecting Confucius's modest and modest attitude towards education and learning.

The story can be understood in three parts. First write about Confucius's encounter with two children's arguments, and point out the time, place, characters, and causes of the story. The two children have two very different views on the distance of the sun from the earth at different times.

Then write about two little fools who use their intuition (sight, touch) that people can experience in their daily lives to clarify their views and refute each other's views.

Finally, it was written that Confucius faced the argument of the two children, and could not adjudicate it, which caused the two children to "laugh". The full text is only about 100 words, but it can give people many inspirations. The characteristics of his language expression are to express the characters and storylines through dialogue descriptions, which show the innocence and loveliness of the two children and the scientific attitude of Confucius's modest and cautious and realistic approach.

At sunrise, the angle between the sun and the ground is 0° 180°.

At noon, the angle between the sun and the ground is theoretically 90°, but this is called the noon solar altitude angle, and the noon solar altitude angle is determined by the latitude position of the place and the position of the direct point of the sun.

At sunset, the angle between the sun and the ground is 0° 180°.

Introduction to the direct sun point:

The direct solar point is the point where the angle of incidence of sunlight on the earth's surface (i.e., the angle of solar altitude) is 90 degrees, and it is the intersection of the geocentric and heliocentric lines and the earth's spherical surface. It is 12 noon at the meridian where the direct point of the sun is located.

The pattern of activity is as follows: at the vernal equinox (around March 21), the direct point of the sun is at the equator (0°), and then moves northward. On the summer solstice (around June 22), the direct point of the sun is on the Tropic of Cancer (23°26 N) and then moves south.

At the autumnal equinox (around September 23), the direct point of the sun is on the equator (0°) and continues to move south. On the winter solstice (around December 22), the direct point of the sun is on the Tropic of Capricorn (23°26 s), after which it moves northward.

The sky was still a light blue, very shallow, very shallow. In the blink of an eye. A red glow appeared where the sky and water met. The range of the red glow slowly expands, getting brighter and brighter. I knew that the sun was about to rise over the horizon, so I couldn't take my eyes off it.

Sure enough, after a while, the little half of the sun's face appeared, very red, but there was no light. The sun seemed to be carrying some kind of burden, slowly, vertically and vertically, and rose vigorously. In the end, it finally broke through the clouds and jumped out of the sea completely, and the color was so lovely red.

In an instant, the crimson round thing shone brightly, making people's eyes hurt. The clouds next to it suddenly shone brightly.

Sometimes the sun hides in the clouds. The sunlight shines directly through the cracks in the clouds to the surface of the water, and it is difficult to distinguish **is water, **is the sky, and only a brilliant light is seen.

Taking the Northern Hemisphere as an example, if the direct point of the sun is in the southern hemisphere, then the position of the sun itself is south of the celestial equator, such as declination -10 degrees, then the position of sunrise in the northern hemisphere is 10 degrees south-east and the sunset position is 10 degrees south-west.

If the direct point of the sun is in the Northern Hemisphere, then the position of the Sun itself is north of the celestial equator, such as declination +15 degrees, then the position of sunrise in the Northern Hemisphere is 15 degrees north-east and the sunset position is 15 degrees north of west.

This is "Liezi. Tang Wen" is a story of two children identifying the day, and it is recommended that you can go to this story. There will be wonderful reviews.

If the story was told in a language class, the answer would be just as close. If the story is told by a physics teacher, you'd better get closer.

In fact, this is an ancient Chinese fable: two people debate whether the sun is near sunrise or the middle of the day. A thinks that the sun appears to be the greatest at sunrise, so the sunrise is near; B thinks that the sun is warmest in the middle of the day, so it is said that the middle of the day is near.

So the two of them argued. In fact, both of them used their own one-sided arguments to judge the issue, so they both came to the wrong conclusions. Just like a blind man touching an elephant, when he touches his ears, he says that an elephant is like a fan, and when he touches his legs, he says that an elephant is like a pillar, and the blind man is right.

As a person who is not blind, you see all of the elephant and say that the elephant is neither like a fan nor a pillar, and the elephant is like an elephant. Going back to the story just now, if we understand the whole situation, we will feel that A and B are actually "blind", both of them are wrong, in fact, the sun is as close to us as the sun is in the sunrise and the sunrise. Both A and B have one-sided arguments such as "it looks bigger at sunrise" and "the sun is warmer in the middle of the day", both of which are one-sided and generalized.

Of course, the meaning of this fable is to tell us some wisdom and truth, and if you use the physicist's perspective to strictly measure how many meters from the sun at sunrise and how many meters from the sun in the middle of the day, it is actually against the original intention of the people in this story.

I suggest you can go to this story when you have time. You'll see great reviews.

The Earth's orbit around the Sun is a nearly circular ellipse, and the Sun is located at a focal point of the elliptical orbit, so that the distance between the Sun and the Earth is constantly changing over the course of a year or even a day.

At the beginning of January every year, the Earth is at the perihelion of its orbit around the Sun, and the distance between the Sun and the Earth reaches a minimum value, which is about 100 million kilometers.

At the beginning of July every year, the Earth is located at the aphelion point of its orbit around the Sun, and the distance between the Sun and the Earth reaches its maximum value, which is about 100 million kilometers.

Compared with the average distance between the Sun and the Earth (100 million km), the difference in the distance between the Sun and the Earth in one year (100 million km) is almost negligible. Then in a single day, the change in the distance between the sun and the earth is even more insignificant.

If you had to compare the distance between the sun and the earth in the morning and at noon, one would think that the sun at noon would be closer, because the morning sun shines from the horizon and is a distance of the radius of the earth than the sun at noon.

Whether this statement is correct or not, let's analyze it.

From the above data, it can be seen that from January to July, in half a year, the distance between the sun and the earth has changed by 5 million kilometers (100 million kilometers minus 100 million kilometers), the change value is 10,000 kilometers per day, from morning to noon for about 6 hours, a quarter of a day, and the distance between the sun and the earth has become about 6868 kilometers, which is greater than the radius of the earth.

If the Earth is moving towards perihelion, from morning to noon, on the one hand, it is indeed closer to the distance of the Earth's radius (more than 6,300 kilometers), and on the other hand, after a quarter of a day, the distance between the Sun and the Earth is also 6,868 kilometers.

But if the earth is moving towards the aphelion, from morning to noon, on the one hand, from the earth to the sun is also close to a distance of about the radius of the earth (more than 6,300 kilometers), but on the other hand, after a quarter of a day, the distance between the sun and the earth is 6,868 kilometers, and the two are superimposed, and the noon is even farther from the sun.

Therefore, whether it is closer to the sun at noon or closer to the sun in the morning depends on what time of year it is.
