Venus, one of the eight planets in the solar system.

According to the order of distance from the sun to the farthest, it is the second one, 0.725 AU from the sun, and its revolution period is 224.71 Earth days.

Venus, the closest planet to Earth (sometimes Mars is even closer).

It is called "Qi Ming" and appears in the eastern sky in the early morning; in the evening, it is called "Chang Geng" and is located on the west side of the sky.

It reaches its maximum brightness just before sunrise or after sunset, and its brightness is second only to the moon in the night sky.

Venus, known in ancient China as Chang Geng, Qiming, Taibai or Taibaijinxing. In ancient Greek mythology it was called Aphrodite. The ancient Romans called it Venus.

On September 2, 2018, Tianyu staged a beautiful celestial phenomenon of the planet Venus "conjoining" the star Spica. The two bright stars will come into close contact and stage a romantic "star attraction" for the public.

Two telescopes in Hawaii and Chile have found possible signs of life in Venus' thick clouds -- a chemical signature of phosphine, according to a study published in the journal Nature Astronomy on September 14, 2020.

Chinese name: Jinxing.

Foreign name: Venus

Aliases: Taibai, Venus, Aphrodite.

Category: Eight planets.

Mass: 4.869×1024kg.

Venus is a terrestrial planet, because its mass is similar to that of the earth, it is sometimes called the "sister star" of the earth.

It is also the only planet in the solar system without a magnetic field. Among the eight planets, the orbit of Venus is the closest to a circle, and the eccentricity is the smallest, only 0.006811.

Taking the earth as one of the vertices of the triangle and connecting Venus and the sun respectively, you will find that this angle is very small, even at the maximum, it is only 48.5°, this is because the orbit of Venus is in the inner side of the orbit of the earth.

Therefore, when we see Venus, it is either in the early morning or in the evening, and it is on the east and west sides of the sky, respectively.

The ancient Chinese called Venus "Taibai" or "Taibaijinxing", also called "Qi Ming" or "Chang Geng" (called "Chang Geng" in the evening and "Qi Ming" in the early morning) The ancient Greeks called it Aphrodite, The goddess of love and beauty in Greek mythology.

In Roman mythology, the goddess of love and beauty is Venus, so Venus is also called Venus.

Venus is the female **** of love and beauty, so the astronomical symbol of Venus is the symbol of women: ♀, some people vividly liken this symbol to "Venus' vanity mirror".

Like the moon, Venus also has periodic round-off changes (phase changes), but because Venus is too far away from the earth, it cannot be seen by the naked eye.

The phase change of Venus was once used by Galileo as strong evidence to prove Copernicus's heliocentric theory.

Venus is the brightest planet in the sky, with a brightness of -3.3 to -4.4, which is 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, while the Romans called it Venus, the goddess of beauty.

In the Bible, Venus symbolizes the dawn and represents Lucifer.

Venus, like Mercury, is the only two large planets in the solar system that do not have natural satellites.

Therefore, there is no "moon" in the night sky on Venus, and the brightest "star" is the Earth.

Since it is relatively close to the sun, the size of the sun seen on Venus is 1.5 times larger than that seen on the earth.

Some people say that Venus is the sister star of the earth. Indeed, from the structural point of view, Venus and the earth have many similarities.

The radius of Venus is about 6073 kilometers, which is only 300 kilometers smaller than the radius of the earth. Its volume is 0.88 times that of the earth, and its mass is 4/5 of that of the earth.
