Venus

Pin It       Today I learned more about planet Venus. I find it interesting so wanted to share some brief information with you.
      The most striking fact is that a single day on Venus is longer than its entire year. It takes Venus 243 Earth days to completely rotate on its axis, but just 225 days to orbit the sun.
      It is the second planet from the sun and is named after the Roman goddess of love and beauty. It is the brightest natural object in the sky after the moon. Venus is a terrestrial planet and is sometimes called Earth's "sister planet" because of their similar size, gravity, and bulk composition. It is both the closest planet to Earth and the planet closest in size to Earth. However, it is very different from Earth in other respects such as the atmospheric pressure or the amount of carbon dioxide in it.
      Concluding with another striking fact, Venus is one of two planets that rotates in reverse. This phenomenon called retrograde motion. Most theories attribute the reverse rotation to an ancient planetary collision.
