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

In order of distance from the sun, it is the second one. It is 0.725 astronomical units away from the sun and its revolution period is 224.71 Earth days.

Venus is the closest planet to Earth and sometimes Mars is even closer.

It is called "Qiming" and appears in the eastern sky in the morning; it is called "Chang Geng" in the west of the sky in the evening.

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

Venus was called Changgeng, Qiming, Taibai or Taibai Venus in ancient China. Known as Aphrodite in ancient Greek mythology. The ancient Romans called it Venus.

On September 2018, 9, Tianyu staged a beautiful celestial phenomenon in which the planet Venus "conjuncts" the star Spica. The two bright stars will come into close contact and stage a romantic scene of "star attraction" for the public.

In a study published in the journal Nature Astronomy on September 2020, 9, two telescopes in Hawaii and Chile discovered the chemical signature of phosphine, a possible sign of life, in the thick clouds of Venus.

Chinese name: Jinxing.

Foreign name: venus

Alias: Taibai, Venus, Aphrodite.

Category: Eight planets.

Mass: 4.869x1024kg.

Venus is a terrestrial planet. Because its mass is similar to that of the Earth, it is sometimes called the Earth's "sister planet."

It is also the only planet in the solar system without a magnetic field. Among the eight planets, Venus' orbit is the closest to a circle, with the smallest eccentricity, 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 the angle is very small, only 48.5° even at its maximum. This is because the orbit of Venus is inside the Earth's orbit.

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 "Taibai Venus", also called "Qiming" or "Chang Geng". When it appeared in the evening, it was called "Chang Geng", and when it appeared in the morning, it was called "Qiming". The ancient Greeks called it Aphrodite, the Greek The mythical goddess of love and beauty.

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

Venus is the female god of love and beauty, so the astronomical symbol of Venus is the symbol of women: some people vividly compare this symbol to "Venus' dressing mirror".

Like the moon, Venus also has periodic phase changes, but because Venus is so far away from the earth, it cannot be seen with the naked eye.

The phase changes of Venus were once used by Galileo as strong evidence to prove Copernicus' heliocentric theory.

Venus is the brightest planet in the sky, with a brightness of 3.3 to 4.4. It is 14 times brighter than the famous Sirius, the brightest star in the sky except the sun. It is 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 without natural satellites.

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

Because it is relatively close to the sun, the size of the sun when viewed from Venus is 1.5 times larger than that seen from Earth.

Some people say that Venus is the sister planet of the Earth. Indeed, from a 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 45 times that of the Earth. Its average density is slightly smaller than that of the Earth.
