Is there really gold on Venus?
The answer is no, there is no gold on Venus. In the atmosphere of Venus, the main components are carbon dioxide and nitrogen, and other small elements. In rock mass, the crust of Venus is mainly composed of silicate minerals, and the inner core may be semi-solid composed of iron and nickel.
The origin of the name Venus.
Venus in China, like Mercury, comes from ancient times. Before the Han dynasty, it was called Taibai, Star or Noisy. In addition, it appeared in the East in the morning, known as Qi Ming, and in the West at night, known as Chang Gung. Until the Western Han Dynasty, when astronomer Sima Qian observed Venus, he found that the color of Venus was white *, so he was associated with the theory of "five elements" at that time and officially named Venus.
In western Roman mythology, the name Venus comes from Venus, the goddess of love and beauty in Roman mythology. It is also the "goddess" in the night sky, because it is bright and easy to see.
How big is Venus?
Venus is about the same size as the earth, and other sizes are similar to the earth, so it is often called the sister star of the earth. The average size of Venus is about 605 1.8km, and that of the earth is about 637 1km.
How far is Venus from the sun? How far is it from the earth?
The average distance between Venus and the sun is about 1 080,000 kilometers, which is almost1times farther than mercury. Because the eccentricity of Venus is much smaller than that of Mercury, its orbit is approximately circular. Venus, like Mars, is a close neighbor of the earth, about 50 million kilometers away from the earth.
The rotation and revolution of Venus
Looking down from the north pole of the earth, you will see that all the planets revolve around the sun in a counterclockwise direction. And most planets rotate counterclockwise, but Venus rotates in the opposite direction. But Venus is not the planet whose rotation direction is clockwise in planets of the solar system as we know it at present. The other planet whose rotation direction is clockwise is Uranus. Venus' rotation is the slowest known planet in planets of the solar system, and it takes about 243.025 days to rotate once. Because it rotates very slowly, it is very close to a sphere. If you watch the sunrise and sunset on Venus, its day will be very long, and it will be a scene of rising in the west and setting in the east. (PS: We often say that "the sun rises in the west" is impossible, which is obviously possible, provided that you say that you observe from the earth. )
Venus revolves in the same direction as the earth and rotates counterclockwise around the sun. It takes about 224.7438+0 days for Venus to make a revolution, while it takes about 365.256 days for the Earth. Because this number of days is not very different from the rotation period, staying on Venus for one day is like staying on Venus for 1 year. (PS: it's similar to "every day is like a year").
Characteristics of Venus
Venus is similar to the earth, with a solid surface and an atmosphere. Some surfaces of Venus are similar to Earth, such as volcanoes, craters and plains, but other features of its surface are quite different. Simply put, the environment on the surface of Venus is much worse than that on the Earth. For example, the atmospheric pressure is about 92 times that of the earth's surface, and it cannot survive even if it is not crushed.
The most striking and attractive feature of Venus is its thick atmosphere. The mass of Venus' atmosphere is about 93 times that of the Earth's, and its main components are carbon dioxide (CO2) and nitrogen, of which carbon dioxide is the most, accounting for about 96.5%. Venus's atmosphere is about 250 kilometers thick, while the earth's atmosphere is more than 1000 kilometers thick. There is another layer above the bottom layer (troposphere) of Venus, where there is a lot of sulfuric acid. The sulfuric acid rain formed in these places drops to 25 kilometers above the ground and will be evaporated by high temperature to form clouds, so the sulfuric acid rain of Venus will never reach the surface of Venus. Due to the opaque clouds formed by sulfuric acid, we can't see the surface of Venus, and we can only understand the surface of Venus through radar imaging. However, some Venus probes have landed on the surface of Venus and taken some photos.
Venus' thick atmosphere is caused by the runaway greenhouse effect. According to research speculation, about 4 billion years ago, Venus once had liquid water similar to our present earth. However, due to the uncontrolled greenhouse effect, water evaporates and other greenhouse gases increase, which may be the fate of the earth in the next few hundred million years.
Venus's powerful greenhouse effect causes its temperature to reach 464 degrees, which is higher than that of Mercury (452 degrees), which is closer to the sun. It is the hottest planet in the solar system.
Venus is different from the earth. It has no strong magnetic field generated by the core. Venus' magnetic field is produced by the interaction between charged particles in the solar wind and particles in Venus' atmosphere.
Can you live on Venus?
The environment on the surface of Venus is very bad, not only hot but also stressful, so it is almost impossible for immigrants to live.
Interestingly, however, the temperature at about 52.5 to 54 kilometers above the surface of Venus is between 20 and 37 degrees, while the atmospheric pressure at 49.5 kilometers is equal to the atmospheric pressure at the earth's sea level. These conditions mean that human beings can live here, but it is located near the sulfuric acid cloud, so we should also consider the influence of sulfuric acid on us.
