Do you know what kind of star Venus is? Can you tell us about it?

Venus in the solar system is called the sister star of the earth. What will happen if we land on it? Venus is the second closest planet to the sun and the sixth largest planet in the solar system. It is a planet surrounded by mountains, valleys and tens of thousands of volcanoes, with a radius of 6,73 kilometers, which is 3 kilometers smaller than radius of the earth. In terms of size, structure and chemical composition, it is similar to the earth, and it is often called the twin brother of the earth. Not only that, Venus reflects 7% of the sunlight it receives, which is why Venus is the second brightest celestial body after the moon in the night sky.

But the shining Venus is not like the moon, but its beautiful surface is toxic, because the whole surface of Venus is covered with clouds of toxic sulfur dioxide, and its atmospheric temperature is over 464 degrees Celsius, which is why humans dare not set foot on this planet, but it can't stop us from exploring Venus. It takes about 1 days to reach Venus from Earth, but finding a landing site on Venus is a big problem, because the space shuttle is surrounded by toxic clouds composed of sulfur dioxide. Not only that, the place with a lower descent will encounter a super strong wind of 36 kilometers per hour, and then descend for dozens of kilometers, the wind will weaken, and you will enter a toxic smog, which is because of the sulfuric acid rain from the clouds on Venus, and the atmosphere of Venus is very hot. So that the sulfuric acid rain evaporates halfway, producing a layer of high-grade acid fog more than 32 kilometers later, and then falling further, the temperature there will increase to more than 3 degrees Celsius, and the pressure will exceed ten times of the earth's sea level. When landing touches the surface, the pressure will be 92 times greater, equivalent to the pressure of two kilometers below the sea level of the earth, and the surface temperature will reach 465 degrees Celsius.

The gravity on Venus is smaller than that on the Earth, because the mass of Venus is 91% of that of the Earth. If people are on it, their weight will be reduced by about 1%. The clouds of Venus reflect 9% sunlight, and there is not enough light on the surface, which makes the surface of Venus dark. There is no oxygen on Venus. Its air consists of 96% carbon dioxide, 3.5% nitrogen and less than 1% carbon monoxide and sulfur dioxide. A day on Venus is equal to 243 earth days, and it takes 225 earth days in a year or around the sun, which means that a day on Venus is longer than a year.
