 Rotation is one complete
turn, or the amount of time it takes for a planet to go
through an entire day and night. One day is 24 hours
long. So if you know how many days it takes for a planet
to complete one rotation, you can easily figure out how
many hours it takes. Simply multiply the number of days
by 24! |
