It takes Earth 24 hours to complete one Day (slightly more than one 360 degree rotation). It takes 365 days 6 hours 9 minutes 9 seconds for Earth to make one revolution around the sun. http://hypertextbook.com/facts/1999/Mitc...
Just think of a top, or record, or wheel. All these things spin around a center point which we call an axis. This type of motion is called rotation, so the amount of time it takes an object to rotate is called a rotational period. It takes the Earth 23 hours, 56 minutes to rotate on its axis. We call the rotational period of Earth a day. Mars takes just a little longer to rotate, at 24 hours, 37 minutes. The Moon is much slower than either Earth or Mars. It takes over 655 hours for the Moon to turn just once on its axis--that's more than 27 days! Second, all the planets and moons in our solar system also move around other things.
