What would happen to the Earth if the brightest star was placed in Proxima Centauri? Will it still s

We know that we live by the sun, we wouldn't exist without the sun, there is not even life on the earth, but if we move the sun closer to us, it will not be appropriate, we will die because it says that it emits a lot of heat, the sun is a fireball far from describing it, it can be a planet like a fireball but tens of thousands of times larger than the earth, so there must be a loss, so if the brightest star is placed in the position of Proxima Centauri, what will happen to the earth? Will it still survive? Of course there will be a big impactA large part of the life on Earth may disappear, and humans may no longer exist, but the creatures that exist in our existence will evolve.

If a planet runs near us in the future, this level of stability will now be broken. A super bright star appears next to us, bringing absolutely more than the cause of light, but light can kill a lot of creatures, we all know that environmental pollution is due to the problem of various garbage emissions, but light can also be polluted, this pollution is not under them at all, we know that driving is the least like high beams, because this time makes many drivers unable to see the road ahead, resulting in irreversible consequences, and this light pollution is more serious than this.

If a star is around us, we encounter more than just itself, we can imagine that it will take billions of years for our solar system to stabilize, and at this time a star will come here, it will change the surrounding magnetic field, and change the gravitational force, etc., which may make the earth go to extinction, let alone human beings.

The current galaxies are very fragile, but it is impossible to pry in the eyes of our human beings, for example, if we throw tens of thousands of them with the strongest nucleus, it will not cause fundamental changes to the earth, only human beings and the surrounding creatures will suffer, and the brightest star comes to our earth, we really have no changes, we can evolve if we have a chance, and we can only perish if we have no chance.

The Earth can survive, Proxima Centauri is a very small hard star, if you put the brightest star next to it, it may lose the ball, and it will be day, not night.

If the brightest star were placed in the position of Proxima Centauri, the Earth would have two suns. At that time, it is estimated that all life on Earth will perish.

The light intensity of the earth will increase a lot, and humans will be affected when they do some delicate work, but it will not affect their survival.

The brightest stars are much larger than the size of the solar system, causing gravitational fluctuations that can even wipe out the Earth.

Our earth is very large, but it is only a planet in space, and it is only a planet, the closest celestial body to us is the moon, it is about 380,000 kilometers away from us, and the nearest luminous celestial body to us is our sun, which is about 100 million kilometers away from the earth, 1.3 million times the volume of the earth, and 330,000 times the mass of the earth, and it takes 8 minutes and 14 seconds for light to run from the surface of the sun to our earth.

Speaking of which, the distance between the Sun and the Earth is quite far, but the closest star to us is light-years away, which means that light needs to travel for 4 years and two and a half months to reach our Earth. But because this star is a red dwarf, it emits very faint light and has an apparent magnitude of only equal magnitude, so even though it is closest to our solar system, we still can't see it with the naked eye.

On a clear night, we look up at the starry sky, without a telescope, in addition to the moon, the brightest celestial body we see is Venus, whose apparent magnitude can reach the highest level, followed by Jupiter, Mars again, Saturn is also very bright, Mercury can only be seen occasionally, Uranus can be seen faintly, and other stars are basically stars except for comets and asteroids.

The brightest star we can see is Sirius, which is located further south in China, and in winter, it forms a large winter triangle with Betelgeuse in Orion and Nanhe III in Canis Minor, which is very conspicuous at night. But Sirius is only light-years away, South-River is about light-years away, and Betelgeuse is about 640 light-years away.

So which star can be seen farthest away from us? Some people say that it is Happis HD61227, this star is more than 40,000 light years away from us, there is a big disagreement about its brightness, at such a distance, its brightness reaches the apparent magnitude, it is incredible, but it is a large mass Cepheid variable star, sometimes the light emitted is very bright, maybe sometimes the apparent magnitude can exceed 6 magnitude and we can witness it, but because the distance is too far, it is basically impossible to notice it by visual method.

The farthest star that can be witnessed is Cygnus HD188209, with an apparent magnitude of about 14,800 light years, which is because it is also a massive variable star, and its physical activity is very intense, so the light emitted is also very strong, so it can be seen by us at such a distance.

However, the most distant objects we can see are not the two of them, but the Andromeda Galaxy and the Triangulum Galaxy, the Andromeda Galaxy is 2.56 million light-years away and has an apparent magnitude of about 4, and the Triangulum Galaxy is 2.95 million light-years away and can barely be seen.

No. Because Proxima Centauri is very far away from us, and we don't have enough technology right now, we can't get there yet.

The closest star to Earth is, of course, the Sun, which is one astronomical unit away from Earth, while Proxima Centauri is light-years away. The closest star to the Sun is Proxima Centauri.

The closest star to Earth is, of course, the Sun, and of course the Sun is a star, there is no doubt about that.

However, the fact that the sun is the closest star to the earth is also common knowledge that too many people know, and there is no need to study it in particular.

Therefore, when people often ask about the closest star to the Earth, they are actually asking about the closest star to the Earth other than the Sun, which is Proxima Centauri.

Of course, in many rather rigorous books, it is stated in the question that the closest star to the earth other than the Sun is Proxima Centauri.

The closest star to Earth is, of course, the Sun. Proxima Centauri is the closest star to the solar system.
