Which Planet has the Longest Day?

Question: Which planets in our solar system have the longest lasting days?

Answer: In our solar system the planet Venus takes the longest to make one full rotation and therefore has the longest day.

One day on Venus lasts the equivalent of 243 days and 26 minutes here on Earth.

After Venus, Mercury has the second longest day taking 58 Earth days, 15 hours, 30 mins and 14 secs. Mars has the third longest at 24 hours, 37 mins and 26 secs.

Our home planet Earth comes in fourth place at 23:56:41.

Despite being the largest planet in the solar system, Jupiter spins extremely fast meaning it can boast the shortest day at just under 10 hours.
