Question:
I my Earth Science book it states that it takes the Earth 23 hours and 56 mins to rotate once around the sun. If that is so then where do the extra 4 minutes go??


Replies:
Rotate about axis, not sun.

In that time, the earth has moved 1/365 in its orbit about the sun. For noon to line up with the sun the next day, we must turn a tiny bit more . . . about 4 minutes worth of rotation.
