Why is Venus called Earth s brother planet

Venus is a very beautiful celestial body. In the night sky, Venus glows with a dazzling white light, like a brilliant diamond. In the West, it is called the most beautiful goddess, Aphrodite, the goddess of love.

Venus has a dense atmosphere on its surface that wraps it tightly. Even large telescopes on Earth cannot see the true face of Venus. So all the secrets about Venus are unknown.

Until the 60s of the 20th century, the great progress of radio technology also created great convenience for the exploration of the astronomical field.

Astronomers have repeatedly measured the time it takes for Venus to orbit the sunEarth days, according to the custom on Earth, should be called a "Venus year". And the time for Venus to rotate one week isEarth days, which should be called a "Venus Day". It can be seen on Venus "One day.""Longer than "one year".

There is a popular saying among the people, "......."Unless the sun hits the west" to describe the impossible, which is indeed impossible on Earth. But in the vast and mysterious universe, right on Venus, the sun and stars rise from the west every day, pass the highest point above the earth's level, and set in the east. And the rotation direction is opposite to that of the Earth and other planets, from east to west.

It is not so easy to observe Venus on Earth, it often appears near the Sun, overwhelmed by the dazzling sunlight. Only when Venus is far away from the Sun can it be viewed. Venus at this time is either near the eastern horizon in the early morning or on the western horizon after sunset.

After September 2003, Venus gradually raised the Sun, the height of the Earth gradually increased, and the brightness gradually increased, and it can be seen in the low southwest sky after sunset.

Due to the autobiography and revolution of the planets, the distance between the Earth and other planets varies, and the closest planet to Earth is Venus. The distance between Venus and Earth varies between 100 million kilometers and 100 million kilometers, so for most of the time, Venus is the closest planet to Earth in the solar system.

The surface of Venus has a thick atmosphere, and its main component is carbon dioxide. And Venus's atmospheric pressure has reached 100 times that of Earth. As a result, Venus often experiences heavy rainfall, but the rain is made up of sulfuric acid.

In such an environment, can you imagine what creatures survive? But scientists still have high hopes for giant stars, because they believe that Venus is in its current situation mainly because it is relatively close to the Sun, and the Sun may have gone through an explosion period before. A strong solar storm causes it to vaporize the water on the surface of Venus, which then carries away the hydrogen and oxygen atoms through the atmosphere.

The heavier carbon dioxide and sulfides were retained, which led to the current situation of Venus.

Venus and the Earth are almost the same in structure, mass and average density, so they are called twin planets with the Earth, but Venus has no water and the temperature on the surface is also very high, making it unsuitable for human habitation.

Venus, like Earth, is a planet with rocks and a dense atmosphere, and Venus is almost as large as Earth, and its rotation period is similar to that of Earth.

They are all close neighbors of the earth. It shares many of the same characteristics as the earth. They all have satellites, they all have moving dunes.

Jinxiang is a star relatively close to our earth, but Venus is not the most likely planet for humans to move in the future, because the atmosphere of Venus is destined to be too high for humans to bear, so the next target is Mars, which is relatively far away. Some of the conditions on the surface of Mars can be detected by probes and can be overcome with the current level of human technology.

Who said that scientists did not go to explore, because it is really far away from our earth, and coupled with the limitations of our technology, it is impossible to carry out large-scale exploration, and now even the moon is not at all.

The current level of scientific and technological development is not enough to realize the action of landing on Venus, so scientists can only do some basic research on Venus. It cannot be explored directly.

Hello, although Venus is the "sister star" of the Earth, because it is similar to the Earth in terms of location, size, and terrain, it cannot but be said to be a wonderful flower at first. Head.

First of all, he has a thick atmosphere, and the pressure at the bottom of it is 90 times greater than that of the earth!

Second, it may have had water before, but then, for various reasons, the water evaporated, leaving poor Venus in a greenhouse effect worse than Earth's.

Third, there is a very high concentration of sulfuric acid clouds in the atmosphere (probably caused by volcanoes), which has caused us humans to land on this planet a great but troublesome ......There are too many, I can't finish it, if you still want to know, just ask, you must be serious!

Venus is one of the eight planets in the solar system, and is the second planet in order of closest to the sun. Its limbs are the closest planet to Earth (sometimes closer to Mars). The ancient Romans called it Venus, in ancient China it was called Chang Gengpei early brother, Qiming, Taibai or Taibai Xing, and in ancient Greek mythology, it was called Aphrodite.

The orbital period is Earth Day.

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