Is there any connection between Sirius, Morning Star, Polaris and Venus?

Hehe, there is no connection, but in ancient China, Sirius is the star of calamity, the star of invaders, the morning star is considered to be the brightest star at night except for the moon (only in ancient times) The North Star is the star of the guide, and Venus is called the Rose Star It is the star of the ancients to see if the world is turbulent If the world changes, the Rose Star has no light.

Broadly speaking, the brightest star is Venus. Venus shines by reflecting sunlight and can reach magnitude -4 at its brightest.

The brightest star is Sirius, the star Canis Major, which is equal in magnitude and is the brightest star in the whole day except the Sun.

The morning star is the name given to Venus's appearance at dawn, because Venus is an intraterrestrial planet (closer to the Sun than the Earth), so it will also appear in the evening, which is called Chang Gung Star.

Venus is now the standard name, in ancient China had other different names for it (except for the star and the star of Chang Gung), the standard title at that time was "Taibai", which was the most commonly used word in ancient astronomical books (basically astrological books), and in the Yuan and Ming dynasties, the title of "Venus" was used more in books.

Here are some of the other names for Venus:

Yin Xing, Dazheng, Yingxing, Star, Stargazing, Overcoat, Dawei, Tai (Bai Gao), Final Star, Daxiang, Dahuan, Shuangxing, Taihao, Xuxing.

Venus is the morning star.

Sirius

The brightest star in the night sky.

Polaris belongs to the brightest star in the constellation Ursa Minor.

It doesn't matter.

Problem description: Why is it said that the appearance of Sirius will lead to disaster?

Analysis: Daystar.

Venus, golden in color, is the brightest star in the sky, as bright as 15 Sirius. Venus, known as "Tai Bai Xing" in ancient China, is called "Morning Star" in the morning, and "Chang Gung Star" if it is dusk.

Sirius. The brightest star in the night sky, the visual magnitude is equal. It is a double star in the constellation Canis Major.

In ancient Egypt, when Sirius rose over the eastern horizon at dawn (a phenomenon known in astronomy as "rising with the sun"), it was the annual time of the Nile flooding, which irrigated large tracts of fertile land on both sides, and the Egyptians began their cultivation again. Since Sirius's presence was closely related to the agricultural production of ancient Egypt, people at that time regarded it as a god and determined the day Sirius rose in the east before dawn as the first day of the year. It can be said that the "Gregorian calendar" that we use today was first born in ancient Egypt.

No, Sirius.

is a star in its own right, and Sirius is known to be a binary star system.

This means that this galaxy has two stars. One of the main-sequence stars (white) is called Sirius A, and the other companion star is called Sirius B, which is a white dwarf.

It is currently about 20 AU away from Sirius A.

The revolution cycle is years. This binary system is about 300 million years old. Sirius VIII's habitable zone is at a distance of 2 to 5 AU from it.

Planets with a distance of less than 2 AU from Sirius A have too high surface temperatures to be inhabitable; Planets outside 5 AU are uninhabitable because the surface temperature is too cold.

Let's take a look at the age of the galaxy. Scientists believe that the age of the Sirius galaxy is about 300 million years old in the solar system.

The age is about 4.5 billion years old. Think about it, how long did it take the solar system to evolve life on Earth to what it is now? Will Siriusians, if they really have, be able to evolve to a more advanced stage than we do in less time?

Of course, perhaps there was a higher level of life on Earth than humans, but it was destroyed by the many celestial collisions that had occurred in the solar system before.

Still, 300 million years is barely enough time for the planet to give birth to life similar to life on Earth. Because, this means that any planet orbiting Sirius A is young, it will have warm, shallow seas, but small land areas, some erosion, and volcanoes. The planet's atmosphere is thick and humid, illuminated by bright and intense Sirius A, which is subjected to intense, bacteria-killing ultraviolet rays.

Only at the shallow bottom of the sea, where strong light cannot reach, some simple bacterial organisms are able to survive and obtain nutrients through hydrothermal vents on the seafloor. It is not known how long it will take for this form of life to evolve into a more complex form of life.

There is also the fact that, in its current composition, Sirius A has a lifespan of only 1 billion years, and now 300 million years have passed. From this, we can speculate that none of the life that formed on any planet located in the habitable zone of the Sirius system will live another 700 million years. All existing planets orbiting Siriusa will be destroyed when their main-sequence star reaches the end of its lifespan.

Therefore, judging by age, the probability of life in the Sirius galaxy is extremely low.

In general, Venus returns to the sky.

Sirius is a star, and its brightness is fixed, etc.

Venus is a planet, it can only be seen by us by reflecting the sun's light, and it may only be more than 10 magnitude when Venus is blind during transit, but generally we observe it in the western sky after sunset or in the eastern sky before dawn, its brightness is basically equal or above, generally speaking, Venus is brighter.

Sirius is a star, a bright star in the southeast of the winter sky, and it may be seen in the southeast of the sky before dawn these days, but I don't recommend it, wait until November, and at 10 p.m. you can see a huge hexagon in the southeast sky, and the brightest one in the southeast, that star is Sirius.

Venus is now located in the western sky after sunset, the brightest one is, it must be seen, now is the best time to observe Venus, the brightness can reach the level, and even the shadow can be found in the best conditions. Because it's a bit exaggerated, some mystics don't think it's Venus, so let's go and see it if you have the chance.

Venus. Because on the one hand, it is very close to the Sun, only 108 million kilometers, and twice as much sunlight hits Venus as it does on Earth, and on the other hand, Venus is surrounded by white and yellow clouds, which reflect about 75 groups of sunlight into space, making it dazzling. Venus can reach the same magnitude at its brightest, about 10,000 times brighter than the faintest star seen by the naked eye, and in the absence of street lights, it is enough to illuminate the way for those who go out early and return late.
