When is the moon bigger than the sun?

1, 12, 13 At 37 a.m., the moon, the earth and the sun line up in a straight line, and the moon is the most round at this time. 12 13 at 6 o'clock in the morning, the distance between the earth and the moon is the shortest in the whole year, only 356,566 kilometers, so the apparent diameter of the moon is the largest, reaching angular seconds, which is 9 angular seconds larger than the apparent diameter of the sun that day.

If you shoot the moon and the sun with a digital camera that day, you will feel that the moon is obviously bigger than the sun.

2. In Fuzhou, Nanchang, Changsha, Guiyang and other areas in China, you can also watch the special scene of "there is a bright moon on your head and no shadow under your feet" in the middle of the month. Because the transit on the moon is only related to longitude, not latitude.

3. Therefore, the transit time of the moon varies from place to place: 120 degrees east longitude, 12, 12, 23: 00; At 0: 34 a.m. on February/3rd, 65438+within the east longitude 1 10 degrees; In the east longitude 100 degree area, it is 65438+ February 65438+March 65438+0: 00 am 15. In Guangzhou, the best time to enjoy the moon is 0: 19 in June, when the horizon of the moon is 86 degrees and the moonlight is the brightest.

The moon is bigger than the sun.

January has 28th, 29th, 30th or 3 1 day. Of course, the moon is bigger than the sun.

The photos of the real earth are too scary. Many people are very satisfied with the earth we live in, but with all kinds of pollution, our earth has become ugly. Next, I will take you to know the horrible photos of the real earth.

The photos of the real earth are too scary 1

Overseas media said that many people's impression of the earth is probably beautiful water blue, but in fact that photo is "PS". Recently, the Japanese meteorological satellite Sunflower 8 took a detailed image of the earth, which is the first photo showing the true color of the earth.

On February 24th, 65438 in Taiwan Province Province, the British Daily Mail reported that the meteorological satellite Sunflower 8 was launched on June 24th, 65438+1October 7th. Recently, an image was taken at a distance of 35790 kilometers from the Earth, showing the details of clouds, oceans and deserts. With super high resolution, this is the first original picture of the earth without any color modification.

Japanese satellites photographed the real face of the earth.

In the past, people's impressions of the water-blue earth came from this photo.

In the public's impression, the water-blue earth is actually a color-corrected photo taken by NASA, which is very different from the gray earth taken by Sunflower 8. However, this so-called "true color" photo does not refer to the image seen by the naked eye, but the real face of the earth in space.

"@ NASA Chinese" also published a photo of the earth without makeup, which surprised netizens. It is uneven, with one concave here and one convex there. Generally speaking, some netizens said it was like a sweet potato, some netizens said it was like a spare tire, and some netizens said it was like a pomegranate.

For this photo, astronomical experts said that the earth is really not an authentic sphere, and its appearance is a bit strange. The reason why the earth is so long is that it not only revolves around the sun, but also rotates. There is both land and water on the surface of the earth. In order to maintain the internal gravity balance, all parties grow into this strange shape under the "struggle".

In fact,

Now, scientific means are developed, which opens up many ways for earth survey. Through actual measurement and analysis, accurate data are finally obtained: the average equatorial radius of the earth is 6378.38 km, and the polar radius is 6356.89 km. It is also found that the Arctic is about 18.9 meters high and the Antarctic is 24 ~ 30 meters low. It seems that the earth is shaped like a pear: its equatorial part protrudes, which is its "pear body"; The North Pole is a bit sharp, like "pear pedicle"; The South Pole is a little concave, like a "pear navel", and is called "pear-shaped earth". To be exact, the earth is a triaxial ellipsoid.

We are always talking about finding extraterrestrial civilization and emigrating to other planets. We are always eager to emigrate to the stars. However, it is pessimistic that up to now, although more than 4000 exoplanets have been discovered, only the earth is still the only known planet with life suitable for human survival. In our stereotype, since man took the first panoramic photo of the earth by satellite 43 years ago, the earth has always been a vibrant blue planet with completely different oceans and continents.

43 years ago, when the first panoramic photo of Zhang Weixing was released in the world, people were shocked by the beauty of the earth, and we were proud of it. More than 70% of the oceans are covered by dense forests on land, which makes our earth like a fairyland, blue and green, colorful and well-defined. Since then, this beautiful image has been engraved in our minds, lingering. Forty-three years have passed, and our earth has not changed at all. Is it really still that beautiful?

In 43 years, the earth has changed. You may not believe it. The earth has changed in less than half a century. It has lost its beauty, even beyond recognition. Yes, the earth has become ugly now, and its appearance has been destroyed by human beings. You may not believe it, but it's true.

Due to the different social division of labor, for most people, there is actually no chance to go directly into space to see the true face of the earth, and even the original photos taken from space at first hand have no chance to see it. All we can see is the processed information and release.

Yes, the earth is beautiful, but that was in 1978, when humans photographed the earth. It's really beautiful, with a clean atmosphere and a vast blue ocean. At that time, the damage caused by human beings to the earth was really small, and there was almost no impact. At that time, the earth had enough ability to digest and deal with environmental problems caused by human beings, but now it has changed, and our destructive power has exceeded the capacity of nature.

In recent years, with the development of human society, we have indeed paid a huge price. Looking at the earth from space, the ocean is not so blue, the land is not so green, the atmosphere is not so normal, and the earth is a little grayish brown.

This is just the interior of the earth. Do you know that outer space is not pure land? In recent years, with the increasing dependence of mankind on artificial satellites, a large number of spacecraft have flown into space and successfully put into normal use, and failed or failed to become space junk. So it is conceivable that our earth has a layer of high-speed garbage. The space environment is inherently dangerous and complicated, especially after there is so much man-made space garbage, the earth is even more dangerous. In particular, we are almost helpless about space junk, and there is no way to recycle it, so "space junk" will only increase.

There are more than 200 countries and regimes in this world, and everyone has complicated relations and interests, but we should remember that the earth is our home. Before we have the ability to create a new star, we should protect it well, because it is the foundation of all of us. We should keep the ocean blue, the sky clean and the earth evergreen. We should not give up environmental protection completely for the sake of economic development, because we must suffer in the end.

Our earth belongs to us, but it belongs to those descendants after all, so do you think we should protect it in time in the face of the deteriorating earth environment?

There is an old Indian proverb that says very well, "Only after cutting down the last tree, catching the last fish and polluting the last river will we understand that money can't be used to eat"!

The biggest day of the moon in 2022

Appeared in the early morning of July 14, 2022. This time is usually from the night of July 13 to the early morning of July 14. This period is basically the best viewing time.

In fact, there is no so-called real best viewing spot in this viewing place. After all, the moon is in the sky, and friends only need to be where they can see the moon. As for the so-called super moon, as the name implies, it is the full moon. July 2022/afternoon of Kloc-0/3 17: 06. At this time, the distance between the moon and the earth is the closest, so the diameter of the moon seen at this time is the largest.

The reason for the formation of the super moon

The formation of the "super moon" stems from the orbital characteristics of the moon's revolution. The moon's orbit around the earth is elliptical, and it is near when it is far away from the earth, about 350 thousand kilometers at the latest and more than 400 thousand kilometers at the farthest, with an average distance of 380 thousand kilometers.

So from the earth, there are "big moon" and "small moon", and their apparent diameters are about one eighth different. Before and after the moon passes through the perigee, if it happens to reach the full moon state, there will be a "super moon".

The largest super moon in 2022

We live on the beautiful earth, but outside the earth is the vast universe, where there are hundreds of millions of stars, planets, clusters and other celestial bodies. So we can often see all kinds of celestial phenomena happening in the sky on the ground, such as the super moon. The super moon is not uncommon. It basically happens every year, sometimes several times a year. So how many super moons will there be in 2022? When exactly?

1, 202 1 When is the maximum moon?

The biggest moon is what we call the super moon. There will be two super moons in 2022, April 27th and May 26th respectively. If the weather is clear and there are no clouds in Wan Li these two nights, it will be easy to see in many areas. Super moon is not uncommon. There are usually four or six super moons every year. There are 6 times in 20 15 years, and the latest time in 2022 is February 9, March 10, April 8 and May 7. Because the moon's orbit around the earth is repetitive, we will meet the super moon every 1 year, 1 month, 18 days, that is, every 383 days.

2. When will the super moon appear in 2022?

The first super moon in 2022 was at 23: 22 on April 27th. At this time, the distance between the moon and the earth is the closest, which is 357378 kilometers, so it will be bigger to the naked eye. The second super moon in 2022 is around May 26th 10, and the distance between the moon and the ground is only 3573 1 1 km, which is the largest in the whole year. However, the second super moon can't be seen in China, but there will be a total lunar eclipse at 19: 08 and 14: 00 this evening, which can be observed by friends in Shanghai, Shenzhen, Guangzhou, Harbin and Beijing.

3. Is the super moon a full moon or a new moon?

According to the original definition of super moon by astrologer RichardNolle in 1979, a full moon or a new moon must be within 90% of the nearest distance to the earth before it can be called a super moon. So the moon at perigee at full moon or new moon can be called super moon, which is called super full moon and super new moon respectively. However, the super moons we usually observe are all super full moons, which will have a more intuitive visual impact.
