Earth’s perpetual rotation, like the daily sunrise and sunset, is a testament to its formation from a primordial cloud of gas and dust. This initial spin, preserved today, dictates the direction of Earth’s rotation. While most planets in our solar system spin counterclockwise like the sun, Venus and Uranus exhibit unique spins. Venus’ thick atmosphere and atmospheric tides have likely slowed its rotation, causing it to spin clockwise. Uranus, on the other hand, spins on its side, possibly due to a collision with a massive object or gravitational influence from a former moon.
