Geographical Features

The sky of Venus is orange. There are also thunder and lightning on Venus, and the largest lightning ever recorded lasted 15 minutes. The atmosphere of Venus is mainly composed of carbon dioxide, with a small amount of nitrogen. The atmospheric pressure of Venus is very strong, 92 times that of the Earth, which is equivalent to the pressure at a depth of 1 kilometer in the Earth's oceans. The presence of large amounts of carbon dioxide causes the greenhouse effect to proceed on a large scale on Venus. Without such a greenhouse effect, the temperature would drop by 400°C.
