Earth's rotation or Earth's spin is the rotation of planet Earth around its own axis, as well as changes in the orientation of the rotation axis in space. Earth rotates eastward, in prograde motion. As viewed from the northern polar star Polaris, Earth turns counterclockwise.
The Solar System formed almost five billion years ago from a turbulent cloud of gas and dust. The motions of the atoms and molecules in that cloud were extremely unlikely to average out to be exactly zero. In essence, there would have been a tendency for them to move, or rotate, in a certain direction.

Feb 14, 2023 · Every 24 hours, the Earth makes a full rotation, spinning west to east, which is why the sun rises in the east and sets in the west and the stars at night appear to move across the sky. Earth spins along an imaginary line between the North Pole and the South Pole called the rotation axis.
