Venus is the second planet from the sun. You may have heard it called Earth's sister because of Venus's diameter, mass, and density are very similar.
Venus is covered with thick clouds that completely hides the surface of the planet. These clouds on Venus reflect 75 percent of the Sun's light. Venus orbits at an average distance of 108.2 million km (67 million miles) from the Sun, and completes one revolution in 224.7 days.
On Venus the sun rises in the west and sets in the east. The reason for this is because Venus rotates in the opposite direction as Earth's rotation. This is called retrograde rotation. Venus atmosphere consist of mostly carbon dioxide, but it also contains other acids. The carbon dioxide traps thermal energy from the sunlight, this process is also known as the greenhouse affect. Venus has the hottest surface of any other planet in the solar system with a temperature of 464 degrees Celsius. Between 1990 and 1992, the Magellan spacecraft mapped the the surface of Venus using radar waves. These radar waves traveled through Venus's clouds and bounced off the planets surface.
