Detailed explanation-1: -The earth takes about 24 hours to complete one rotation around its axis. The period of rotation is known as the earthday.
Detailed explanation-2: -The Earth rotates on its axis relative to the sun every 24.0 hours mean solar time, with an inclination of 23.45 degrees from the plane of its orbit around the sun.
Detailed explanation-3: -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.
