Since every planet travels at a different speed and has a different orbital path in regard to size and shape, the length of a year can vary greatly from planet to planet. Another way to measure a day is to count the amount of time it takes for a planet to completely spin around and make one full rotation. The Earth is the only planet with an approximately 24-hour day.

A Day On Venus: Also known as “Earth’s Twin”, Venus is the second closest planet to our Sun – ranging from 107,477,000 km at perihelion to 108,939,000 km at aphelion.
If you google this question then you might get a different answer since some websites have a strange idea of what a day is. Just to be clear, this answer to ‘which planet has the longest day’ is based on this criteria: a planets day is how long it takes it to complete one rotation on its axis. This is called a sidereal day .
A day on Jupiter Rotation of Planets: You might know that all of the planets in our solar system rotate, which means that they are spinning around. Jupiter has a small axial tilt of only 3.13 degrees, meaning it has little seasonal variation during its 11.86-year-long orbit of the Sun. Which Planet has the Longest Day? We know how long an Earth day is, but how about the other planets in our solar system? After Venus, Mercury has the second longest day taking 58 Earth days, 15 hours, 30 mins and 14 secs.
