Solution
The answer is "the difference between solar and sidereal time."
Here's why:
-
The Earth rotates on its axis and also orbits around the Sun. These two movements are not synchronized.
-
A sidereal day is the time it takes for the Earth to rotate once on its axis relative to the stars. This is approximately 23 hours, 56 minutes.
-
A solar day is the time it takes for the Earth to rotate once on its axis relative to the Sun. This is approximately 24 hours.
-
The difference between these two times is due to the fact that the Earth moves a little bit along its orbit around the Sun during the time it takes to complete one full rotation on its axis.
-
Therefore, the fact that the Earth has moved along its orbit in the time it took to rotate once is the reason for the difference between solar and sidereal time.
