Detailed explanation-1: -The time it takes Earth to rotate so the sun appears in the same position in the sky, known as a solar day, is 24 hours. However, the time it takes Earth to complete one full rotation on its axis with respect to distant stars is actually 23 hours 56 minutes 4.091 seconds, known as a sidereal … day.
Detailed explanation-2: -24 hours is what we think of as being a complete day, and the time it takes to transition from day to night and back again. But in truth, it actually takes the Earth 23 hours, 56 minutes, and 4.09 seconds to turn rotate once on its axis compared to the background stars.
Detailed explanation-3: -The sidereal day happens each time Earth completes a 360-degree rotation. That takes 23 hours and 56 minutes. The solar day-the one humans count in the calendar-happens when Earth spins just a little further, and the sun is at the same point in the sky as it was 24 hours ago.
