Why Does Venus Spin in a Different Direction?
by Emily Bautista, age 13
There is a lot about space that we have not discovered. One mystery we have not explained is why Venus spins in a different direction from other planets, east to west.
Venus spins in the opposite direction from the sun. This is called retrograde rotation. It is one of two planets that spin differently from the other planets, the other being Uranus. Unlike Earth, the sun moves west to east across the sky. That is because it spins the opposite way that Earth does.
That is not the only difference between the way Venus and Earth spin. It takes 243 Earth days for Venus to spin fully, making it slowest out of all the planets in our solar system. A year on Venus takes 225 Earth days, making the planet's year shorter than its day. Crazy, right?
Now you may be wondering, “Why does Venus rotate in a different direction than the rest of the planets?” Although scientists are unsure of an explanation, they have developed some theories. One of those theories is that a large object, maybe a planet, hit Venus and changed its rotation. However, this is not a fact, just a theory.
The search for answers continues, maybe one day we can figure out the reason for this mystery of Venus’ rotation.
