A Day on Venus Lasts Longer Than a Year on Venus

Venus is the kind of neighbor who does things completely on their own schedule ? and by their own schedule, we mean a wildly inconvenient one. This second planet from the Sun takes only about 225 Earth days to complete one full orbit around the Sun. That is its year. Seems reasonable so far.

Here is where things get strange: Venus rotates on its own axis so slowly that a single day on Venus ? one full spin ? takes about 243 Earth days. That means by the time Venus finishes one rotation, it has already lapped itself around the Sun. A Venusian day is genuinely longer than a Venusian year. Calendars on Venus would be a logistical nightmare.

To make it even weirder, Venus rotates backwards compared to most planets. If you stood on Venus (briefly, and with extraordinary heat protection), the Sun would rise in the west and set in the east. Scientists believe a massive ancient collision may be responsible for this retrograde spin, though Venus has never offered an official explanation.

So the next time someone complains that the days feel too long, just remind them they could have been born on Venus, where every single morning technically belongs to last year.
