Earth perpetually moves in various respects: rotating on its axis roughly every 24 hours, revolving around the Sun yearly, and moving within the Milky Way galaxy. Each of these motions occurs on different scales and affects how we quantify Earth's speed and position in the universe. While its rotation and revolution create our day-night cycle, the larger scale movements connect Earth's motion to the broader cosmos, indicating intricate interactions within galaxies and intergalactic environments.
The Earth completes a full 360° rotation approximately once a day, while also moving around the Sun, resulting in complex motion relative to various reference points.
Our entire Solar System, including Earth, moves through the Milky Way galaxy, which orbits around the galactic center on timescales much longer than humanity's existence.
