As you see stars apparently lined with Earth’s axis (Polaris in the North), you believe stars are moving around this point. It’s an optical effect. Actually, stars move but not around Polaris. The Earth’s rotation movement is faster than most of us think, about 460 meters per second or roughly 1,000 miles per hour (in earth’s surface respect to the planet’s center, at the equator ).
Every video is made from stacking pictures taken in Time-Lapses. Photography give us the chance to realize the rotation movement.
