Stars appear to be rising and setting, as well as the planets, Moon and the Sun. And with more precise instruments, we can see some stars appearing to move back and forth relative to other ones. As we'll see below, we can explain those movements through the Earth's rotation and movement through its orbit.

Why does it look like stars are moving?

There are actually two different reasons why stars appear to move across our sky. The first is because the Earth is spinning and second because the Earth itself is moving around the Sun. ... At the same time as the Earth is moving around the sun it is spinning on it own axis (once a day).

Is it normal for stars to move?

The stars are not fixed, but are constantly moving. If you factor out the daily arcing motion of the stars across the sky due to the earth's rotation, you end up with a pattern of stars that seems to never change. ... But sensitive instruments can detect their movement.
