Detailed explanation-1: -The time it takes for a planet or other celestial object to complete one spin around its axis is called its rotation period. Earth’s rotation period is about 24 hours, or one day.
Detailed explanation-2: -The earth rotates once every 23 hours, 56 minutes and 4.09053 seconds, called the sidereal period, and its circumference is roughly 40, 075 kilometers. Thus, the surface of the earth at the equator moves at a speed of 460 meters per second–or roughly 1, 000 miles per hour.
Detailed explanation-3: -It takes 24 hours to complete one rotation, which is why there are 24 hours in one day.
Detailed explanation-4: -Mercury: 58d 16h, 10.83 km/h. Venus: 243d 26m, 6.52 km/h. Earth: 23h 56m, 1574 km/h. Mars: 24h 36m, 866 km/h. Jupiter: 9h 55m, 45, 583 km/h. Saturn: 10h 33m, 36, 840 km/h. Uranus: 17h 14m, 14, 794 km/h. Neptune: 16h, 9, 719 km/h. 06-Feb-2020
