365 days in a year
366 days in a leap year.
It takes earth exactly one day to rotate around the axis.
About 27.3 days.
For one axial rotation it takes 243 Earth days.
The earth's moon rotates on its axis in exactly the same period of time required for it to revolve around the earth once in its orbit ... 27.32 days.
27 1/2 days for both.
It takes 27.3 days for the Moon to revolve around the Earth, and the same amount of time to rotate on its axis.
10 days
About .997 days per full earth rotation on its own axis.
The moon takes about 27.3 days to spin around its axis once, which is the same amount of time it takes to complete one orbit around Earth. This synchronous rotation is why we always see the same face of the moon from Earth.
well, if there are about 365 days/year and 1 rotation of the Earth on its axis equals 1 day then it rotates about 365 times? No, that's how many days we see. Try a quarter and dime on the table and ask, if the earth rotates on its own axis one time, how many days would we see? Hint, the earth rotates in the same direction on its own axis as its direction of revolution around the sun.
A Mercurian "day" the (time it takes it go spin once on it's axis) is equal to 58.65 earth days. Mercury turns on it's axis very, very slowly.
about 63 earth days
