What interesting fact is associated with a day on Venus?

A day on Venus is indeed longer than a year on Venus, which is a fascinating aspect of the planet's rotation and orbit. Venus takes about 243 Earth days to complete one rotation on its axis, meaning a single day (the time it takes for Venus to spin once) lasts significantly longer than its orbital period around the Sun, which is about 225 Earth days. This unique characteristic leads to the intriguing situation where Venus's day is greater in duration than its year.

The other answers do not reflect this unusual dynamic: the first option misstates the relationship between a day and a year, while the third option incorrectly claims they are equal. The last option suggests that a day lasts only 24 hours, which is not the case for Venus. Thus, understanding that a day is longer than a year on Venus highlights the peculiarities of planetary motion in our solar system.
