Venus, the second planet in our solar system, is a very fascinating planet. Though all of the planets in our solar system each have different characteristics, Venus is very unique on its own. Venus is around the same size as Earth, though it is about 405 miles smaller than Earth in diameter. Though they have almost the same diameter, Venus has developed into a scorching hot planet with a dense atmosphere made up of many different gases causing it to develop an extreme greenhouse effect. Venus has the strongest greenhouse effect in our solar system, causing its surface temperatures to be as hot as 467 degrees Celsius. Venus is the second planet closest to our sun, but it is the hottest planet in our solar system.
Along with the extreme greenhouse effect in Venus's atmosphere, it also has intense winds that circle around the planet. Venus has a phenomenon known as super-rotation, meaning that these winds circle around the planet faster than its actual rotation in the cloud tops. A rotation on Venus is around 243 Earth days, while the winds can travel around the planet in around 4 Earth days.
This photo shows the thick atmosphere of Venus and the different layers of clouds from 21 miles to 31 miles. Each color represents the height of each cloud, for example the red clouds are the highest while the green and blue are lower. These clouds are extremely thick, about 15 miles, and they are also made up of sulfuric acid, which also contributes to the greenhouse effect.
As stated before, Venus's sidereal day is about 243 Earth days, meaning it has an extremely slow rotation. In addition, Venus's sidereal day is actually slower than the time it takes Venus to orbit the sun. Venus takes around 225 Earth days to orbit the sun. Scientists believe that this is caused by the strong pull from the sun.
Venus also has retrograde rotation, meaning that it rotates clockwise around its axis. In our solar system most of the planets rotate in the same direction as they orbit, but Venus is one of the only planets in our solar system that rotates backwards, along with Uranus. This means that the sun rises in the west and sets in the east, which is opposite of Earth. Scientists are unsure for the reason of this strange rotation, but they believe that Venus once rotated the same way as Earth but was somehow flipped 180 degrees on its axis, meaning that it is upside down.
