When it comes to the planets in our solar system, each one has its own unique characteristics that set it apart from the rest. One such characteristic is the length of a planet's day, or the time it takes for the planet to complete one full rotation on its axis. So, which planet has the longest day?

The planet with the longest day in our solar system is Venus. Venus has an incredibly slow rotation, taking about 243 Earth days to complete just one full rotation. This means that a day on Venus is actually longer than a year on Venus, as it takes Venus only about 225 Earth days to orbit the Sun. This slow rotation results in Venus having the longest day of any planet in our solar system.

If you're curious about why Venus has such a long day, it all comes down to its unique rotation. Venus rotates on its axis in the opposite direction to most other planets in our solar system, a phenomenon known as retrograde rotation. This slow and backward rotation is thought to have been caused by a large impact in Venus's past that set it spinning in the opposite direction.

For more information on Venus and its long day, you can visit NASA's website. Here you can find detailed information about Venus's rotation, as well as other interesting facts about this fascinating planet.

So, if you ever find yourself wondering which planet has the longest day, look no further than Venus. Its slow and backwards rotation make it a unique and intriguing member of our solar system. And who knows, maybe one day we'll uncover even more secrets about this mysterious planet and its long day.
