A day on Venus is longer than a year on Venus.
Yes — it's true.A single day on Venus is longer than a full year on Venus.Here’s why it feels so bizarre:A "year" on Venus (one complete orbit around the Sun) lasts 225 Earth days.
A "day" on Venus (one full rotation on its axis, relative to the stars) lasts 243 Earth days.
So if you stood on the surface, the Sun would rise in the west, crawl slowly across the sky, and set in the east after you had already completed more than one lap around the Sun.Even stranger details:Venus rotates backwards (retrograde rotation) compared to most planets, which is why the Sun rises in the west.
A solar day on Venus (from one sunrise to the next) is even longer: roughly 117 Earth days.
Because of this, a Venusian "day" is so slow that you could theoretically walk fast enough to keep the Sun fixed in the sky for a while.
Venus is the only planet in our Solar System where a day is longer than its year — a weird cosmic quirk caused by its extremely thick atmosphere and gravitational interactions that have gradually slowed its spin over billions of years.In short: on Venus, you’d celebrate more birthdays than sunrises.
