Venus is one of the eight planets in the solar system. According to the order from near to far, it is the second astronomical unit from the sun. It is the closest planet to the earth (Mars is sometimes closer). Ancient Romans called it Venus, ancient China called it Chang Geng, Qiming, Taibai or Taibai Venus, and ancient Greek mythology called it Aphrodite. This is Earth Day during the revolutionary period.
Venus gives people the feeling that it is a suffocating planet. Carbon dioxide accounts for 97% of its atmospheric composition, which has a very strong greenhouse effect, and the surface temperature reaches more than 400 degrees Celsius.
In addition, the atmospheric pressure on Venus is 90 times that of the earth's surface, and the terrible sulfuric acid rain is daunting. Venus, in such a harsh environment, was one of the commanding heights of the US-Soviet hegemony in the 1960s and 1970s. The Soviet Union has made great discoveries and achievements in exploring Venus. The West even once called Venus "the planet of the Soviet Union".
Like Uranus, Venus rotates in the opposite direction to other planets, from east to west. Therefore, from Venus, the sun rises in the west and sets in the east. The reverse rotation of Venus may have been caused by the collision of Venus with other asteroids a long time ago. In addition to this unusual reverse rotation, Venus is a little unusual.
Venus's rotation period and orbit are synchronous, so when the two planets are closest, Venus always faces the earth with the same face.
However, there are many differences among these basic similarities. Venus's atmospheric composition is mostly carbon dioxide, so its surface has a strong greenhouse effect. Its atmospheric pressure is about 90 times that of the earth, which is almost equivalent to the water pressure of one kilometer below the surface of the earth.
There is no water on the surface of Venus and there is no water in the air. The main component of its cloud is sulfuric acid, which is much higher than the height of the earth cloud. Due to the high atmospheric pressure, the wind speed on Venus is relatively slow. In other words, the surface of Venus is neither affected by wind nor washed by rain. Therefore, the volcanic characteristics of Venus can obviously last for a long time.
