Subsequently, one may also ask, why does it look like the stars are moving?
Because the earth spins around its North Pole-South Pole axis, the stars in the sky appear to follow circular paths around these poles.
Subsequently, question is, what does it mean when you see a star flickering? In simple terms, twinkling of stars is caused by the passing of light through different layers of a turbulent atmosphere. Most scintillation effects are caused by anomalous atmospheric refraction caused by small-scale fluctuations in air density usually related to temperature gradients.
In respect to this, why does it look like the sky is moving?
The Sun, Moon, and planets appear to move across the sky much like the stars. Because of the Earth's rotation, everything in the sky seems to move together, turning once around us every 24 hours.
Why do we see the same stars?
As Earth spins on its axis, we, as Earth-bound observers, spin past this background of distant stars. As Earth spins, the stars appear to move across our night sky from east to west, for the same reason that our Sun appears to “rise” in the east and “set” in the west.
