Venus is the second planet from the sun and neighbor to Earth. Besides the moon, Venus is the brightest object that can be seen in the night sky.
Astronomers believe that Earth and Venus may have comparable histories due to their similar size, mass, and volume. However, researchers wonder why Venus is so different compared to Earth today.
Venus’s rotation is unlike any other planet in the solar system. It also has no moons. One rotation on Earth is 24 hours, but one on Venus is about 243 Earth days. Venus’s rotation around the sun is about 117 Earth days. Venus is the only planet that rotates longer around its axis than once around the sun. Every other planet rotates clockwise, while Venus and Uranus rotate counterclockwise.
Venus is constantly covered in layers of thick clouds. It has a huge atmosphere surrounded by layers of carbon dioxide. This hefty atmosphere traps heat, making Venus the hottest planet in the solar system, even hotter than Mercury—the planet closest to the sun. Additionally, Venus’ surface has lots of volcanic activity.
Venus is a fascinating planet and has many unique features. Scientists have already sent 20 robotic spacecraft and continue to send more. There is much more to learn about this unique planet.
