Why is the weather on Venus different from that on Earth?

There is a dense atmosphere and clouds around 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%. Huge corrosive acid rain often falls. The surface temperature of Venus is as high as 500℃, and the atmospheric pressure is about 90 times that of the earth (equivalent to the pressure in the 900-meter deep sea of the earth).

Venus rotates in the same direction as Uranus, contrary to other planets, from east to west. Therefore, on Venus, the sun rises in the west and sets in the east. Venus' orbit around the sun is an ellipse that is very close to a perfect circle, and the deviation is less than 1, which is close to the ecliptic plane. Its revolution speed is about 35 kilometers per second, and that of period of revolution is about 224.70 days. But its rotation period is 243 days, which means that Venus' rotation sidereal day is getting longer every day. However, according to the earth's standards, if a sunrise is counted as a day, the year on Venus is far less than 243 days. This is because Venus rotates in the opposite direction; On Venus, the sunrise is in the west and the sunset is in the east. The alternation of day and night from one sunrise to the next is only 1 16.75 days on earth. Venus and the sun have a maximum viewing angle of no more than 48 on the earth, so Venus will not appear in the night sky all night. In our country, people call Venus at dawn the morning star and Venus at dusk the evening star.
