Venus, like Mercury, is the only two big planets in the solar system without natural satellites. So there is no "moon" in the night sky on Venus, and the brightest "star" is the earth. Because it is close to the sun, the size of the sun seen from Venus is 1.5 times larger than that seen from the earth.
Some people say that Venus is the twin sister of the earth. Indeed, from the structural point of view, Venus and the Earth have many similarities. Venus has a radius of about 6,073 kilometers, only 300 kilometers smaller than 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. The average density is slightly less than that of the earth. But the environment between them is very different: the surface temperature of Venus is very high and there is no liquid water. Coupled with cruel natural conditions such as extremely high atmospheric pressure and severe hypoxia, Venus cannot have any life. So Venus and the Earth are just sisters.
There is a dense atmosphere and clouds around Venus. These clouds cast a mysterious veil on the surface of Venus. Only with the help of radio telescopes can we cross this atmosphere and see the true face of Venus. In the atmosphere of Venus, carbon dioxide is the most, accounting for more than 97%. At the same time, there is a layer of concentrated sulfuric acid with a thickness of 20 to 30 kilometers.
