Do you know Venus(金星)?Of the eight planets in the solar system, Venus is the nearest one to us. Venus also refers to the Roman goddess of love and beauty. In Greek her name was Aphrodite. Venus and the earth are almost the same size, and you would weigh almost the same on both planets. If you were 70pounds on the earth, you would be 63 pounds on Venus.

Venus is an" unfriendly" planet. Because. of its thick cloud, you can't see the surface(表面). In many ways, Venus is like the earth. It has active volcanoes(火山), mountains and valleys(峡谷)too. But Venus is too hot for life. It has the hottest temperature of the planets in our solar system, about 480C. Besides, the earth lets heat out through volcanoes, hot springs, but Venus lets heat out in a different way. For a longtime most scientists thought that Venus probably had plants, animals, and possibly even human beings. However, because Venus is so hot, it is impossible for anything to live there.
