Venus Spins Backward So the Sun Rises in the West
Venus is the only planet in our solar system that rotates clockwise, meaning its sun rises in the west and sets in the east. Scientists believe this odd spin was caused by a colossal ancient impact that flipped the planet on its side and then slowed its rotation to a crawl.
💡 Fun detail:
A single day on Venus lasts longer than a year on Venus—243 Earth days to turn once compared to 225 Earth days to orbit the sun.
