What is that bright star in the south now?

Huang Chengyun expert :

It is a planet – Jupiter.

The landlord may be suspicious, right, Jupiter can also see? It's still so bright. That's right, Venus and Jupiter are the brightest of the five planets, surpassing all the stars.

I'll list the evidence that can prove its identity below, and the landlord will see if it meets the requirements:

1.Position and Motion: Jupiter now rises after about 18 o'clock and appears above the eastern horizon.

It travels at a speed of about 15° per hour and is oriented westward, possibly slightly southerly. If this criterion is satisfied, it proves that it is not an intra-atmosphere object. Today it is very close to the moon and very easy to identify.

2.Brightness: More than 10 times brighter than the second brightest star in the sky, no other celestial body can achieve such brightness (Venus is not visible lately).

3.Blink: The landlord may wish to take a closer look at this celestial object to see if it blinks, I believe it will not. If my guess is correct, it's an intrasolar system.

4.Telescope observations: Two pieces of conclusive evidence: four Galilean moons and a circular plane, both of which should be easily visible. With binoculars you may only be able to see the former.

The landlord may wish to find a telescope and keep an eye on the star in the middle of the night. See if what I'm saying is accurate.

It's cloudy here, and we can't see it. If anything, I hope it is Vega, who illuminates the mood of the lonely prodigal son.

Depending on when you meet, it is Venus in the morning and evening.

1. Seeing a very bright star in the eastern night sky is the morning star.

This is what we call Venus.

2. Venus is one of the eight major planets of the solar system.

one, in order of proximal to farthest from the sun, is the second. In ancient China, it was also known as "Chang Geng", "Qiming" or "Taibai". The orbital period is Earth Day.

The brightness in the night sky is second only to that of the moon.

In second place, Venus reaches its brightest only a little before sunrise or a little after sunset.

3. Venus is a terrestrial planet, sometimes called the "sister star" of the earth, and the only planet in the solar system without a magnetic field. Among the eight planets, Venus's orbit is the closest to a circle, and the eccentricity is the smallest, only.

4. The vertex of the Earth as the angle connects Venus and the Sun respectively, and you will find that this grinding angle is very small, even if it is the maximum, because the orbit of Venus is on the inner side of the Earth's orbit. Therefore, when we see Venus, it is either early in the morning or late in the evening, and it is on the east and west sides of the sky, respectively.

5. Venus, like the Moon, also has periodic changes in the circle (phase change), but because Venus is too far away from the Earth, it cannot be seen with the naked eye. About the phase change of Venus, once by Galileo.

As proof of Copernicus.

Strong evidence for heliocentrism.

6. If you have a bird's-eye view of the solar system from the north pole of the sun, all the planets rotate in an anticlockwise direction, but Venus rotates clockwise, and Venus rotates clockwise.

The night sky is second brightest after the Moon, and Venus reaches its brightest only time before sunrise or after sunset. It sometimes appears in the eastern sky early in the morning and is called "enlightenment"; In the evening, it is on the western side of the sky.

There is an unusually bright star shining in the southwest sky, which is the famous Venus. Experts in astronomical science and hail remind that from September to December, Venus ushers in the observation season, and on December 4, Venus will reach its brightest of the year.

Venus is the close neighbor of the earth, and China called it "Taibai" in ancient times. When it appears in the morning, people call it the "morning star" or "morning star"; When it appears at dusk, people call it the "Chang Geng Star" or "Evening Star". Normally, Venus is the brightest object of the whole day except for the Sun and the Moon, and can reach so much at its brightest.

Profile of the star:

Stars refer to celestial bodies in the universe that are visible to the naked eye. The activity of the energy inside the star makes the star irregularly shaped. Stars can be broadly divided into planets, stars, comets, white dwarfs, etc.

The brightest planet with broken sails is Venus, the fastest star traveling at more than 2.4 million kilometers per hour, and h1504+65 is the hottest white dwarf. <>

The brightest star in the western sky in the evening was Venus. Venus is one of the eight planets in the solar system, and is the second planet in order of closest to the sun.

How stars are formed:

1. Neutron stars, after the formation of stars, stars with masses greater than the Sun may form neutron stars after collapse. The formation time depends on the mass of the star and the rate of spontaneous ignition.

2. Planets are formed by the impact and aggregation of asteroids in the universe, or by the separation of large planets. It does not emit light on its own, we can see it because it reflects the light of other stars, and it is formed after the star is formed, or it is captured by other stars after it is formed.

3. The formation of the Weihui cluster is basically the same as that of the planets.

4. The stellar turbulent land is due to the nebula dust floating in the universe absorbing the asteroids or other substances next to it, and then it is aggregated and compressed to the center. As for how long it will take, it depends on the size and mass of the nebula. The larger the size and the higher the mass, the faster it will be formed, which will be between hundreds of millions and billions of years.
