Venus is the second planet from the sun. When viewed from a telescope Venusexhibits phases similar to that of the moon. Venus rotates on an axis like earthbut slower and in a direction opposite Earth's. The atmosphere on Venus is comprisedmostly of carbon dioxide (CO2) and a small percentage of the atmosphereis nitrogen. Venus has many clouds, which are made up of high concentrations ofsulfuric acid.
Water and water vapor are extremely rare on Venus due to its high surface temperaturethat can approach 758 K (900 °F). This extreme temperature is causedby the greenhouse effect. As sunlight heats Venus' surface, the surface radiatesinfrared energy that is kept from escaping the planet by dense carbon dioxideatmosphere.
The atmospheric pressure on Venus is 90 times greater than that of the Earth.The surface of Venus is very mountainous and has many volcanoes, some of whichare higher than Mt. Everest. The gravity on Venus is similar to that of Earthbut the mass of the atmosphere would crush a person and the air on Venus is unbreathable.

| Arnett, Bill. Venus. Nine Planets Solar System Tour. University of Arizona. | "This dense atmosphere produces a run-away greenhouse effect that raises Venus' surface temperature by about 400 degrees to over 740 K (hot enough to melt lead). Venus' surface is actually hotter than Mercury's despite being nearly twice as far from the Sun." | 740 K |
