Rotation period : about 58.5 Earth days. That's known as a "sidereal day".
There is also the "solar day". That's about 176 Earth days.
58.6 Earth days
one full day on mercury is 88 earth days
A day on Mercury is 58.646 Earth days long
88 Earth Days
It takes about 59 Earth days (58.66 days) for Mercury to make one rotation.However, its "day" is extended due to the extremely short orbital period of 88 Earth days : a "sunrise to sunrise" solar day is 176 Earth days long (2 Mercury years).This is the source of the saying "On Mercury, a day is twice as long as a year."
58.6 Earth days
The answer is 58.646 day.
117 earth days is equal to 1 Venus day. (including night time.) Mercury's day is the equivalent to 176 earth days.
One year on Mercury is about 88 Earth days long, 3/4 of a Mercurian day.
Year: 88 Earth days. Rotation period (sidereal day): 58.6 Earth days. Solar day: 176 Earth days.
The answer is 58.646 day.
