The temperature of the topmost layer of Venus's clouds is around 55 F. (13 C.), and the entire surface gets as hot as 870 F. (465 C.)—hotter than that of any other planet. There is no water on Venus's surface—any water would evaporate because of the extremely high temperature. Earth's plant and animal life could not survive there. Scientists are not sure there is any life form on the planet. Most astronomers think that the high temperature is caused by Venus's atmosphere.
