23 Hours 25 Minutes
Name: Christina H.
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??
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.
