In the starry sky on a winter night, after dusk, in the direction of south west, there is an extreme

Now that Jupiter is close to the Sun, Venus is the brightest star in the sky, about 14 times brighter than Sirius at its brightest. On the 15th, Venus was at its greatest eastern elongation, reaching an angular distance of 47° from the Sun, and the horizon height at sunset was also 37°, and the brightness continued to increase thereafter, reaching its brightest v=1 on February 19

Dusk is south-west and so bright.

That's Chang Gung Xing.

Actually, it's the morning star, it's Venus.

Venus Profile. It is mentioned in the first paragraph.

Venus Venus is one of the eight planets, the closest planet to the Earth, called Chang Gung as the evening star, and Qiming as the morning star. Venus is the brightest object in the whole day after the Sun and Moon, with 14 times the luminosity of the Sirius.

Venus's rotation is peculiar, it is the only large planet in the solar system that rotates in a reverse direction, from east to west. Venus's orbit around the Sun is a very close to a perfectly circular ellipse that coincides with the ecliptic plane, and on February 19, the horizon of Venus at sunset drops to about 30°, but its brightness is up to the same level.

Chang Gung Star Morning Star is Venus.

It's the morning star, he's Venus, also called Taibai, or Taibai, just because when you see it in the morning, it's Qiming, and when you see it at night, it's called Chang Gung, and it's called differently, and he's the third brightest star in the sky besides the sun and moon.

Sirius, the star A of Canis Major, is located in the constellation Canis Major. Sirius is the brightest star of the day except the Sun, but it is darker than Venus and Jupiter.

Most of the time it is brighter than Mars.

Sirius is a blue-white main-sequence star with a white dwarf.

A companion star, the center of mass of the system is about light-years from Earth. Among them, Sirius B, the companion star of the white dwarf, is the earliest white dwarf observed by mankind and one of the most massive white dwarf stars. Sirius's English name is Sirius, which means "scorched" in Greek, because the ancients believed that when Sirius and the sun rose at the same time, it was the summer spike, and the light of Sirius and the light of the sun were combined to be the reason for the hot summer weather.

On summer nights, the bright star that appears in the southeast may be Antares, also known as "Great Fire", which is about 550 light-years from the Sun.

Antares, scientific name: Scorpio.

Located at the tail of the constellation Scorpio, it is the loneliest first magnitude star of the whole day, but there are many bright second-magnitude stars in its vicinity, and it is also the brightest star in the Scorpio region. In ancient China, it was also known as the Great Fire, which belonged to the Seven Houses of the Oriental Canglong.

Antares, or the dragon's heart, is used to determine the seasons.

Antares is a famous red supergiant that emits fiery red light, located due south at dusk in May every year, with the highest position; At dusk in July, the position of Antares Mars gradually descends westward from the mid-heavens, "knowing that the heat is gradually receding and autumn is coming". The Book of Songs

The "July Flowing Fire" refers to this star.

To the left and right, the brightest star in the southeast is Vega, the fifth brightest star seen on Earth after the Sun, located in the constellation Lyra; To the right of Vega is a bright star, which is the Cowherd in the constellation Aquila. The bright star to the left of Vega is Tianjin IV in the constellation Cygnus. The three stars together form a right triangle, which is a very important symbol of the summer night sky, also known as the summer triangle.

Extended information: Vega is the brightest star in the constellation Lyra, and several nearby stars are connected together to form a lyre, which Westerners call Lyra. It moves closer to the Sun at a speed of 14 kilometers per second.

More than 10,000 years ago, Vega was once the North Star, and due to the precession of the Earth's axis, Polaris was the constellation Ursa Minor. However, in 10,000 years, Vega will return to its prominent position on the North Star. Scientists estimate that around 14,000 AD, the North Celestial Pole will point to Vega, when Vega will replace Shaowei Zengba (Cepheus Star) as the North Star, and the South Pole Star will also move to the position of the second brightest star in the sky, the Old Man Star.

Around 4000 AD, Shaowei Zengba will replace Ursa Minor, as the North Star) Next to Vega, there are four stars forming a small diamond shape. Legend has it that this small diamond shape is the shuttle used by the Weaver Girl to weave cloth, and while the Weaver Girl is weaving, she looks up at the Cowherd (River Drum 2) and her two sons (River Drum 1 and River Drum 3) on the east bank of the Milky Way affectionately.

Qiming is also called Chang Gengxing and Venus. Every evening when the sun sets and the sky is about to fall into darkness, a very bright star will appear in the southwest, which appears earliest and very bright, this is Venus, also known as Chang Gung Star, Morning Star. Venus sets later than the sun, so it is called Chang Gengxing, because it comes out earlier than the sun, so it is also called the morning star.

In ancient China, Venus was called "Taibai Jujube Withered Venus", "Taibai", and "Qiming". One of the eight planets, it is sometimes the morning star, which appears in the eastern sky before dawn and is called "enlightenment"; Sometimes it is a twilight star, which appears in the western sky after dusk and is called "Chang Gung".

Types of Stars:

Planets are nearly spherical objects that orbit stars in elliptical orbits. The planet itself cannot emit light, but shines due to the reflection of stellar light, and the orbit of the planet has three characteristics: coplanarity, isotropy and near-circularity.

A comet is a unique cloud-like appearance of a celestial body that moves around the sun and its brightness and shape change with the solar distance. Comets are divided into three parts: the nucleus, the coma, and the tail.

Meteoroids are particles of particles that are small in the rocks of the solar system, ranging from sand and dust to boulders, and are dry and granular, and after the meteoroid enters the atmosphere of the Earth or other planets, it is called a meteor when it shines and is seen in its path. <>

The brightest star in the west in the evening is Venus. Venus, among the eight planets in the solar system, is the second planet from the sun outward, Venus is called Taibai, Xingxing or Dahuan in ancient China, and appears in the east in the morning called Qiming, and appears in the west at night called Chang Geng.

Astral characteristics: 1. Venus is a terrestrial planet, because its mass is similar to that of the earth, and it is sometimes called the sister star of the earth. It is also the only planet in the solar system that does not have a magnetic field. Among the eight planets, Venus's orbit is the closest to a circle, and the eccentricity is the smallest, only.

2. Take the Earth as one of the vertices of the triangle and connect Venus and the Sun respectively, and you will find that this angle is very small, even if it is the largest, it is only, 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.

3. The ancient Chinese called Venus Taibai or Taibai Star, also known as Qiming or Chang Gung when it appeared in the evening, and called Qiming when it appeared in the early morning) The ancient Greeks called Aphrodite, the goddess of love and beauty in Greek mythology. In Roman mythology, the goddess of love and beauty was Venus, so Venus was also called Venus. Venus is the female goddess of love and beauty, so the astronomical symbol of Venus is a sign of femininity, and some people have likened this symbol to Venus's vanity mirror. <>

1. The brightest star in the western sky every evening is Venus.

2. Venus is a terrestrial planet, because its mass is similar to that of the Earth, and it is sometimes called the "sister star" of the Earth by people who swim Chishu. It is also the only planet in the solar system that does not have a magnetic field. Venus is the brightest planet in the whole day, with the highest brightness, 14 times brighter than the famous Sirius (the brightest star in the sky except the Sun), like a dazzling diamond, so the ancient Greeks called it Aphrodite, the goddess of love and beauty, and the Romans called it Venus, the goddess of beauty.

In the Bible, Venus symbolizes the dawn and represents Danchalucifer. Venus, like Mercury, is the only two large planets in the solar system that do not have a natural satellite. Therefore, there is no "moon" in the night sky on Venus, and the brightest "star" is the Earth.

Due to its proximity to the Sun, when viewed from Venus, the Sun is twice the size of the Sun as seen from Earth.

The brightest star in the southeast direction in the evening is Jupiter. Jupiter is the solar system.

The largest planet in China, with a volume of more than 1,300 times that of the Earth and a mass of more than 300 times that of the Earth, it is also known as "Jupiter Spike", the "king of the gods" in Roman mythology.

meaning. Jupiter opposition" refers to the phenomenon that the Earth and Jupiter are in a straight line when they reunite with the Sun when they are orbiting in their respective orbits, that is, the phenomenon that Jupiter and the Sun's ecliptic longitude are 180 degrees apart, which is called "opposition" in astronomy. At opposition to Jupiter, Jupiter is in the constellation Sagittarius, rising from the southeastern horizon at 8 p.m. and rising due south at midnight, about 20 degrees above the horizon.

It fell from the southwest at 4 a.m.
