Venus is the second planet from the sun. When viewed from a telescope Venus exhibits phases similar to that of the moon. Venus rotates on an axis like earth but slower and in a direction opposite Earth's. The atmosphere on Venus is comprised mostly of carbon dioxide (CO2) and a small percentage of the atmosphere is nitrogen. Venus has many clouds, which are made up of high concentrations of sulfuric acid.

Water and water vapor are extremely rare on Venus due to its high surface temperature that can approach 758 K (900 F). This extreme temperature is caused by the greenhouse effect. As sunlight heats Venus' surface, the surface radiates infrared energy that is kept from escaping the planet by dense carbon dioxide atmosphere.

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 which are higher than Mt. Everest. The gravity on Venus is similar to that of Earth but the mass of the atmosphere would crush a person and the air on Venus is unbreathable.
