Which Planet’s Days Are Longer Than Its Years?
Neptune
Jupiter
Venus
Mercury


Answer: Venus

In the family of planets that make up our solar system, Venus is a peculiarity among peculiarities. The roughly Earth-sized but scorching planet has an average surface temperature of 860F and an atmosphere composed almost entirely (96.5%) of carbon dioxide.

As far as planetary extremes go, those things aren’t particularly peculiar. What is rather peculiar is that if you were to somehow, in spite of the harsh conditions, set up camp on Venus you’d be treated to days that run longer than years. Venus rotates on its axis only once every 243 Earth days but orbits the sun once every 224.65 Earth days–you’d wait longer between sun rises than you would to completely orbit the sun.
