Question

Quizplus · Accepted Answer

A star being directly overhead again in 23 hours 56 minutes is due to Earth's rotation period with respect to the stars, known as a sidereal day. This is the time it takes for the Earth to rotate once relative to the background stars, which is about 4 minutes shorter than the solar day of 24 hours.
