A day on Venus is longer than a year on Venus

🤷 This changes nothingFact Battle

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.

Why this is surprising

We intuitively assume a day is always shorter than a year, but planetary mechanics can completely break that assumption.

A day on Venus (243 Earth days) is longer than its entire year (225 Earth days). The sun rises in the west there too. 🪐 #SpaceFact #OddlyHuman
