When something just spins in a circle it's called "rotating" and when something spins around another object it's called "revolving" but when something rotates and revolves it's called "orbiting."
The earth takes 24 hours to rotate which is one earth day.
And a full circle around the sun is one year.
On Mercury it takes 59 earth days to rotate one time.
And just under 30 earth days of being hot and 30 earth days of cold dark.
All that to say that it's 88 earth days to make one Mercury year.
Well that is enough on Mercury for today.
