How Many Days does it take Mercury to Complete One Revolution?

According to Abyss.UOregon.edu, Mercury takes around 88 days for Mercury to complete a single revolution around the sun. Clearly, Mercury is a lot faster at revolving around the sun than planet Earth, which takes around 365 days to make its way around. 

As we said above, the planet Mercury completes one revolution, or orbit around the sun, in approximately 88 days (in reality, it is probably around 87.969 days if you want to be exact.)   Mercury also rotates on its axis and completes one rotation every 58.6 days.

So, why is Mercury so fast and how does its rotation schedule affect how time passes on the planet?

• Mercury is much closer to the sun than Earth, which results in a much faster year. 
• However, according to Enchanted Learning, the amount of time that it takes for the planet mercury to experience one “earth day,” (meaning the amount of time between noon and noon or one complete revolution of the planet) is 176 earth days.
• Essentially, this means that time is much slower on Mercury- to live through one complete day on Mercury, you would have lived through almost a third of a year on Earth. 

The manner in which time passes on mercury is referred to as “mercury days." It takes three “mercury days” to experience one spin of the planet from high noon to high noon, as opposed to on earth, where this same rotation takes only 24 hours. 

These "mercury days" are also called “solar days” because they track the amount of time that a person or individual would perceive that it took the sun to go around the planet one full time.
