Is UY bright when placed on Proxima Centauri? Does it have an impact on the planet?

On this subject, I think astronomers have actually divided the brightness of the more than 6,000 stars visible to the naked eye in the sky into six magnitudes, which are actually called asterisksThe brightness of the faintest star we can see with the naked eye is about 6, and the brightness is 5, which is a little brighter than 6, and so on, the fewer the number of stars, the brighter the star may be, however, we find that the apparent magnitude of the star does not reflect the true brightness of the star.

For example, the shield UY that we mentioned is actually 340,000 times brighter than the Sun, but due to his distance, its apparent brightness is only 10 6. We can't see it directly with the naked eye, so this sun should be very bright, because it is only 1.5 billion kilometers away from us. Thus, to reflect the true brightness of a star, astronomers define an absolute star, which is measured by placing all the stars 32 6 light-years from Earth.

In this way, the star is like an athlete on the same running line, if there is a real glow, then it may naturally be cold, if you place the Shield UY at 32 6 light years, its star brightness is 6 2, at this time, his brightness is about 6 3 times that of Venus, theoretically the effect of this Shield UY at this distance can be devastating, but it seems that we humans are lucky.

There should be no possibility of a supernova explosion within 30 light years, and the mass of Sirius is not enough to resist Betelgeuse's explosion, but it is more than 640 light years away from Earth, and the impact on our Earth is almost non-existent, but the impact of the brightness of Uy on the Earth in the constellation Shield is more difficult to assess here, how serious the impact it will have on our Earth.

Regarding the question of whether the position of the Shield Constellation UY in the position of Proxima Centauri has an impact on the Earth, it will be explained here today.

The brightness is not very large, and our observations are very dim at present, and they have no effect on the earth, I think it is too far away.

The position of Proxima Centauri is very bright and can be seen from Earth. It has no impact on the earth, after all, the shield UY will not **.

Shield seat UY. Because the volume of the Shield UY is larger, hundreds of thousands of times that of the Sun, the brightness of the Shield UY is greater.

The sun is brighter because it is much larger and the light it emits is visible to the naked eye.

UY is the largest star ever observed, 1,800 times larger than the Sun; Proxima Centauri is the closest star (light-years) to Earth, but we can't see Proxima Centauri with the naked eye because Proxima Centauri is so dim that it has an apparent magnitude of 11.

There are nearly 200 billion stars in our galaxy, and the farthest single star can be seen with the naked eye, as far away as 7,000 light-years, but the closest Proxima Centauri is invisible to our naked eye, because Proxima Centauri is a red dwarf and is at the lowest level of star mass. UY is a red supergiant star in the constellation Shield, and the parameters of both are as follows:

Uy Shield: 5,100 light-years from Earth, 1,800 times the diameter of the Sun, absolute magnitude, apparent magnitude 8 10.

Proxima Centauri: Light-years from Earth, 1 7 in diameter from the Sun, absolute magnitude, apparent magnitude 11.

If we put Uy Shield in the position of Proxima Centauri, what would the night sky of Earth look like?

There is a conversion between absolute magnitude and apparent magnitude as follows:

Place Uy Uri in the position of Proxima Centauri, and the apparent magnitude of Uy will be as high as:

m=m-5log10(d0/d)=；

The lower the magnitude value, the higher the brightness, the apparent magnitude 6 is the limit visible to the naked eye, the apparent magnitude of Venus is at its brightest, the brightest star in the whole day except the Sun is Sirius, and the apparent magnitude of the Full Moon is -13.

Therefore, if you put the Shield Uy in the position of Proxima Centauri, the brightness is already very close to the brightness of the full moon, and in the night sky of the earth, it is like a small moon, even during the day, it is visible to the naked eye.

Uy Shield is very unstable, the period of light change is 740 days, each light change will release a huge amount of energy, if the Earth is only 4 light years away from Uy Shield, then life on Earth will be devastated, and Uy Shield has reached the end of stellar evolution, and it is expected that in the next few million years, it will end this life cycle in the form of a supernova.

The constellation Shield is the largest star we can observe, and if it is placed in the position of Proxima Centauri, it will probably reach the brightness of the full moon at its brightest.

The Earth will be able to observe another star that is more shiny. Well, for example, there might be another sun on Earth. Therefore, the shield seat UY is also very shiny.

If the Shield Constellation UV is placed in the position of Proxima Centauri, it will be very dazzling when observed on Earth, and it can be compared with the light of the Sun.

UY is the largest star currently observable by humans. Whereas, Proxima Centauri is the closest star to the Sun. If the shield star UY is really in the Proxima Centauri position.

Humans can. Humans look at him the same way they look at the sun, but he is very unstable, and the earth will be devastated.

UY is a star larger than the Sun, and if you put it in Proxima Centauri, you may see a star larger than the Sun during the day, and there may be two moons in the sky.

UY is the largest star ever discovered, and if it were to be swapped with the Sun, all the solar system bodies within Saturn's orbit would be swallowed by it.

In a situation where UY can hold 6450 trillion Earths or 5 billion Suns, most people only focus on its size "close to the limit of stars" and ignore its equally amazing brightness, in fact, the brightness of UY is 300,000 times brighter than the Sun, and the Sun is compared to "how can the fluorescence of rotten grass be as bright as the moon of the heart of heaven?" ”

However, although the volume and brightness of the Scutellus UY are very "top-notch", because it is far away from 5100 light-years (the previous data is 9500 light-years), its light is "drowned" by other stars near the solar system before reaching the Earth, so we can't see the Uy of Shields with our eyes, and only with the help of professional astronomical equipment can we see the dotted Constellation Uy.

Light-years away from the solar system is the famous Proxima centauri star, so although Proxima Centauri is the closest star to the solar system, the degree of nuclear fusion reaction in the red dwarf is very "peaceful" compared to the sun, which is destined to the brightness of Proxima Centauri will not be too high (absolute magnitude, apparent magnitude 11, has exceeded the limit of the human eye 6), so we on the earth can not directly see this "closest to the solar system" star.

With neither the "largest star" nor the "nearest star" visible, can we see UY in the constellation Shield if they switch places from each other?

Data calculations show that after moving Uy Shieldi to Proxima Centauri, its 300,000 times the brightness of the Sun will make the apparent magnitude of Uy Shieldi reach, and the apparent magnitude of the Sun is only -12, and the apparent magnitude of Venus is only at its brightest.

Therefore, if we move the Uy of Shields to Proxima Centauri, the night sky of the Earth will have an additional dazzling source of light, and people can even use the light emitted by the Uy of Shields to see the way when the Moon is obscured by clouds.

But in the long run, because UY is already in the red supergiant stage, and its core mass has surpassed the neutron stage, it is likely that the constellation Shield will explode supernova in a few million years, and the core region will also collapse into a black hole.

This is equivalent to placing a medium on a planet next to the earth, and the next planet will release some energy through this medium, causing the earth to be damaged. The entire universe and galaxies will also undergo a series of changes due to this medium.

If we put the Shield Constellation UY in the position of Proxima Centauri, the Earth will not be far away from us, in fact, the constellation is a pattern composed of a projection of the stars, of course, the direction between them is close, so it looks farther away.

In this case, there will be a certain amount of damage and damage to the terrain, and the corresponding galaxies will have some special reactions, and the earth will be affected, which will cause harm to the earth.

What is the effect, Proxima Centauri is 4 light-years away from us, and the diameter of the constellation Shield is about 2.5 billion kilometers, even if it is increased by ten times the diameter, the impact is minimal.

According to scientists, UY is the largest star in the universe, and if it were placed in Proxima Centauri, all the celestial bodies in the solar system would probably be swallowed by it.

Chen's model of the universe: "Depth Analysis of Dielectric Waves" has the answer.

If the Shield url is placed in the position of Proxima Centauri, it will affect the normal operation of the Earth, because this galaxy can be said to be gradually evolving towards a black hole, and its mass exploration has been very obvious, and in the next few hundred or thousands of years, it is entirely possible that it will become a black hole, and a black hole can swallow everything.

It won't make a difference. Because the Uy of the Shield constellation is still very far away from the Earth, its influence is still negligible compared to the Sun.

If this is the case, the Earth could be destroyed by the occurrence of a supernova in the constellation Shield, and become a place of nothing.

UY is the largest star, and if we were to replace Proxima Centauri with UY Shield, two suns would appear on Earth.
