Why does a supermoon occur on May 6?

The supermoon refers to the state of the moon in close proximity to the earth, according to the British "Daily Mail" on March 8**, on March 19, 2011, the moon will reach the closest position to the earth in 19 years, when it will be only more than 350,000 kilometers away from the earth, and it will look unusually huge. The incident has sparked a debate in the astronomical community: many fear that a "supermoon" will bring extreme weather and even catastrophic disasters; Many scientists claim that such fears are unfounded, even "conspiracy theories" of "amateur scientists".

The supermoon refers to the state that the moon is relatively close to the earth, and generally only refers to the moon at the moment of perigee. However, it is not a very rigorous scientific term, and the so-called "closer" is more vague and relative. As the Moon orbits the Earth, its orbit is elliptical, so the distance between the Moon and the Earth varies, and the size of the Moon as seen by people varies.

When the Moon orbits at perigee, it is closest to the Earth, and the Moon is the largest and brightest Moon seen on Earth during the cycle. Since the orbital plane is closer to the ecliptic plane than near the Earth's equatorial plane, and the Earth-Moon system is a complex system influenced by multiple celestial bodies, the orbit of this synodic month (the minimum effective time required between two identical moon phases) and the next synodic moon will inevitably change, and among the perigee of several synodic months, there must be one that is closer to the Earth's surface, and it can be seen to become the so-called "supermoon".

Judging from the past astronomical data, the recorded occurrence time of the "supermoon" seems to be regular; However, the Earth-Moon distance criterion for judging supermoons is not so easy to grasp, there is no so-called critical distance, and it seems that "case law" can only be implemented according to the previous statement. And this adjudication power is often in the influential **, with a certain degree of subjective arbitrariness and hype. The concept of a "supermoon" is "too vague" and not 'bright' at all.

The Moon is the only satellite of the Earth, and fine dating of the Moon and Earth's rocks shows that the Moon was formed at an age of 4.5 billion years, while the Earth was formed at an age of about 100 million years. The age of the rocks on the surface of the Moon is generally greater than 3.1 billion years, indicating that the evolution of the Moon took place mainly within 1.5 billion years of its formation. The Moon is now a celestial body that is close to depletion of its internal energy and is close to dead, with only very weak moonquake activity.

It's almost every 2 years, and the perimoon is a lot closer to the moon on this day, it seems to be 35-360,000 kilometers!

Normally, it is more than 380,000 kilometers, and the moon's orbit is elliptical

It's still not as fast as it is being copied

The appearance of a supermoon heralds a storm with **. Although the term "supermoon" originated in astrology, astrologer Richard Knoll also gave some examples of supermoons being associated with major storms and events. But scientists have confirmed:

The appearance of a supermoon only increases its tidal force on the Earth's oceans, with little effect on the movement of underground plates.

How is this Supermoon different?

The "Supermoon" that appeared last night was rounded at 19:52. At 7:23 on June 15, the moon's perigee was less than 12 hours apart from the perigee of the moon, and the distance between the moon and the earth was less than 360,000 kilometers, so the apparent diameter of the lunar surface of this full moon was very large, and it was the "second largest full moon" this year.

According to statistics, the supermoon on November 14, 2016 will be slightly larger than the 26th time in January 1948 of the last century, and the next supermoon on November 25, 2034 will be a little larger than in 2016. As a result, the largest supermoon of the century will occur 32 years later on December 6, 2052.

A supermoon is not a natural disaster. Speaking of the "Supermoon", I don't think everyone will find it strange. People have been following it for as long as there is news about it, and there are a lot of rumors about it.

Among them, there is a proverb that says that the "supermoon" is artificially created. It is also said that a supermoon can cause natural disasters such as **, because when the supermoon appeared in 2011, there was a strong ** in Japan. So, what is the truth?

What exactly is the word supermoon? In 1979, American astrologer Richard Noel defined a supermoon as a phenomenon in which the moon is near perigee when it is new or full. Because the Moon's orbit around the Earth is a non-standard ellipse, the Moon orbits the Earth more than 12 times a year, and each of the Moon's laps passes through perigee, the most recent of which is about 356,000 kilometers from the Earth.

If the Moon passes through perigee and happens to be close to the Full Moon, the Full Moon will appear very large and is known as a Supermoon.

However, supermoons are not mysterious. On average, there will be 4 to 6 supermoons a year. When the Full Moon rises above the horizon (i.e., near the Moon), we see the Moon appear larger and brighter than it would have been when it had risen to the zenith.

The near moon is nearly 14% larger than the far moon, and its brightness will also increase by 30%. However, because the distance between the Earth and the Moon is much greater than the slight changes in the Moon's orbit, changes in the size and brightness of the Moon are not easily noticeable to the human eye.

When the Supermoon appeared in March 2011, Japan experienced a magnitude of intensity**. Many people suspect that this is the cause of the Supermoon. Does a supermoon really cause natural disasters such as **?

In this regard, Zhao Zhiheng, an expert in astronomy education and president of the Tianjin Astronomical Society, said that there is no evidence that the distance between the Earth and the Moon is related to ** or volcanic eruptions. Even if volcanic eruptions and ** occur, it is due to the earth itself. At present, the scientific community generally believes that changes in the distance between the Earth and the Moon only affect the tides of the rivers and seas.

The occurrence of 2 supermoons this year is actually not unusual, because the probability of supermoons occurring 2-4 times in a year is about 2-4, and this year's supermoon is a little bigger than usual, so it is very concerned by us, you can actually take a look at the introduction I generated!

Why did 2 Supermoons happen this year? "Supermoons" are not uncommon, once or twice a year, and more often than three or four. There will be two "supermoons" this year, the first is the children's full moon on June 14, with an apparent aperture of 33 24, the moment of hope occurs at 19:52, and the moment of the moon's perigee is 7:23 on June 15, and the distance between the two is less than 12 hours; The second is the children's full moon on July 14, the visual aperture reaches 33 35, the time of hope occurs at 2:38 on the 14th, and the moment of the moon's perigee is 17:06 on July 13, and the distance between the two is less than 10 hours, so the children's full moon has become the "older children's full moon" of the whole year.

The "Supermoon" is when the full moon is around perigee, so it looks big and bright. When the moon and the sun are on opposite sides of the earth, and the yellow of the moon and the sun are 180 degrees apart from each other, the moon seen on the earth is very round, which is called the "child full moon".

of every lunar month.

Ten. Four, ten.

The fifth, sixteenth, and even seventeenth are the times when a child's full moon is likely to occur. A calendar year typically has 12 or 13 child full moons. If the Full Moon is near perigee, the Moon will appear large and round, and it is called a "Supermoon" or "Very Child Full Moon".

Is the Supermoon highest on July 14? This supermoon is considered to be the largest of the year. A "supermoon" generally refers to a full moon that occurs when the moon is at perigee.

The Moon orbits around the Earth about a dozen times a year, and on several occasions it coincides with a child's full moon.

The lunar orbit, which revolves closely around the Earth, is elliptical. In its operation, it has been far and close to the Earth, about 3.5 billion kilometers as recently as possible, and about 4 billion kilometers further away. The distance between the two is about 5.1 billion kilometers, so there is a large moon and a small moon as seen from the Earth.

This is because both moons orbit to the closest point to the earth, where you can see the moon in a large and round place, and have the best viewing angle, so it appears.

The appearance of a supermoon depends on two key factors: proximity and roundness. This year, the moon is closer to the Earth at this point in time, so supermoons are more likely to occur.

The change in climate has brought about such a climate. Let people see a different natural phenomenon, and this is how the moon came about.

This year, the moon has moved very close to the Earth twice for the best viewing angle, and the moon appears large and round, so it appears twice.

There are one to four Supermoons a year, and this year there will be two, the first one on June 14 and the second one on July 14, less than ten hours apart, so there are only two Supermoons.

It is not uncommon for a "supermoon" to occur in a year, because the condition for the occurrence of a "supermoon" is that it is near perigee at the time of the full moon.

Why does the Moon look the tallest and roundest of the year on May 6? Experts say filial piety is because, at 11:34 p.m. on May 6, the moon is closest to the earth, only 356955 kilometers, which is the closest time for the earth to the moon this year. The apparent diameter of the Moon reaches arc minutes, which is larger than the apparent diameter of the Sun at any other time.

At 11:35 p.m. on May 6, the moon, the earth, and the sun are approximately lined up in a straight line, and the moon is at its fullest. It is rare for the moon to be at its roundest and the moon to be closest to the earth on the same day throughout the year, and the difference between the two is only one minute, which is very rare, and it will not occur several times in 100 years.

Due to the fact that the nearest moon of the earth is approximately lined up with the sun, the earth and the moon throughout the year, and the two occur almost at the same time, the tides and maximum tidal ranges of rivers and seas around the world caused by this will also cause the water level of the rivers and rivers to be poor, and the drainage of the city will not be smooth, resulting in "flooded streets". From May 6 to 8, it will be significantly higher than normal for the same time of year, but there will be no disaster.

In addition, experts note that there are not many chances of seeing the moon during the day. If it is clear at night, the public can still look up at the moon and enjoy the full moon of the year, which is the largest and roundest of the year.

A supermoon is a supermoon that is close to the Earth because it coincides with the full moon and is closest to the Earth.

I think it's likely that it will, but it's still unknown.

This is very likely, because the phenomenon of supermoons is really scary.

Generally speaking, supermoons increase the tides and do cause some natural disasters for humans.

I don't think that's going to happen, and it might benefit the planet and people.

Let's start with a little bit of the moon. The Moon is a satellite of the Earth, which orbits and rotates. Its orbital period around the Earth is Days, and the rotational period is exactly equal to the Orbital Period, so the Moon is always facing the Earth on one side.

The Moon is 363,300 km to 405493 km from Earth, so there are two points in each orbital period: perigee and apogee (astronomical term). The moon changes in the sky every day, and this change is called the moon phase.

The phases of the moon are made up of: the first quarter, the first quarter, the hope, and the second quarter, which is what we call the crescent, the full moon, and the absence of the moon. The moon phase occurs in relation to the sun at an angle in the moon's orbit around the earth.

Now that we have a basic understanding of the moon, then it is easy for us to understand the supermoon. A supermoon is actually the moon when it is at perigee, which happens to be the fifteenth or sixteenth lunar calendar. Of course, the proximity to the earth is large, and the apogee to the earth is small.

But in fact, when reporting, it is important for the publisher to give you a time to watch. Because they will surely let you look when the moon rises, and not when the moon is due south.

Because due south, you can't tell if the moon is bigger than it used to be. The reason is actually very simple, when the moon rises, the moonlight is oblique to your position, and the moonlight will be scattered through the thick atmosphere of the earth, and the moon will appear larger. And when the moon is due south, the light is directly on your position, so it will be much smaller than when it rises in the east.

So you won't feel how much bigger the moon is than it used to be when it is due south. After all, you can't feel it at all if it's 4% bigger.

When the Moon reaches perigee and coincides with the Full Moon, it will appear 12% larger than usual and brighter. This is called a supermoon. But the term supermoon was not accepted by astronomers, and in astronomy it was called the "periapsis synodic moon".

When the periapsis occurs in the Synodic Moon, because the Moon, the Earth and the Sun are in a straight line, and the Moon is closer to the Earth, the tidal forces are also a little greater than usual, and the tides that occur at this time will be larger than usual.
