Is Venus suitable for human habitation? What are the similarities between the earth and Venus?

Venus is one of the eight planets, and it is the second planet in the order from near to far from the sun. It is the closest planet to the earth. China called it Taibai or Taibai Venus in ancient times. It is sometimes the morning star, which appears in the eastern sky before dawn and is called "Qi Ming". Sometimes it is a dim star, which appears in the western sky after dusk and is called Chang Gung. Venus is the brightest star except the sun and the moon in the whole day, with the maximum brightness of -4.4, which is 14 times brighter than the famous Sirius (the brightest star except the sun in the whole day), like a dazzling diamond, so the ancient Greeks called it Aphrodite, the goddess of love and beauty, while the Romans called it Venus, the god of beauty.

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.
