A day on Venus is longer than a year on Venus
Some trivia is so bizarre it forces you to rethink your entire understanding of the world. Check out the fact below, see how others reacted, and scroll down to dive into the verified science and history behind it.
Venus rotates so slowly on its axis that it takes 243 Earth days to complete one full rotation — longer than its 225-day orbit around the Sun. This means on Venus, you'd experience a sunrise before you'd completed your first year. To make it stranger, Venus rotates backwards compared to most planets, so the sun rises in the west.
We intuitively assume a day is always shorter than a year, but planetary mechanics can completely break that assumption.
