The rotational period of the earth is 23.9345 hours or .99727 days. If you take the left over time in a day and multiply it times 365.256 you get almost exacly 24 hours. that means that the earth has rotated 24hours that aren't included in the 365 days. another way to think about it is to visualize the earth and the sun. If the earth rotated 23.9345 hours and moved in its rotation, the sun would not be at noon but would be roughly 3min 56 sec from noon. if we take the 3 min 56 sec extra the earth has to spin and multiply it by 365.256 days we find that the earth rotated one complete extra time. therefore a day is not equal to a rotation but 1 and (1/365.256) rotations. My science teacher doesn't believe me and i've done my reasearch so could you please help me out?
Re: Doesn' t the earth rotate 366.256 times in a year but only have 365.256 day
