Best Answer

The Earth rotates once every 23 hours 56 minutes and 4 seconds.

This is called the sidereal day (as compared to the "fixed stars").

However, the solar day takes 24 hours, because the Earth is also revolving in orbit around the Sun, and takes another 4 minutes to completely turn back to facing the Sun.
