How Many Degrees Does the Earth Rotate in One Hour?
The Earth rotates approximately 15 degrees in one hour. This is determined by dividing the number of degrees in one full rotation (360) by the number of hours in one day.
Of the other planets in the solar system, Mars is the most similar to Earth in terms of degrees rotated in one hour. A day on Mars is 24 hours and 39 minutes, and it moves about 14.6 degrees every hour.
Venus has the slowest rotation of solar system's planets. One day on Venus is 243 Earth days, or 5,832 hours. Venus rotates just a sixth of one degree every hour. Jupiter has the fastest rotation, spinning a full rotation in just under 10 Earth hours and moving approximately 36 degrees every hour.
