The planet Venus is, with respect to its size, very similar to earth. The minimum distance between earth and Venus is only 38.3 million kilometers. However, the surface of Venus is covered with clouds, and for a long time very little was known regarding this surface. In 1956, measurements of microwaves emitted by the lower Venus atmosphere showed that a temperature of approximately 600 K existed near the Venus surface. It was finally recognized that the high temperature of Venus is related to the greenhouse effect. The mechanisms by which this effect can produce the observed high Venus temperatures are discussed in detail. More information about Venus was obtained mainly in connection with Mariner 10, Pioneer Venus Orbiter, and Venera space missions. According to the current state of knowledge regarding the Venus surface, this surface is a basalt rock desert with temperatures above 450 C, a pressure comparable to that on earth at a depth of 1000 m below the surface of the sea, and a carbon dioxide atmosphere.
