Adding on to the great inputs already provided by the other experts here us a bit more on what causes the apparent motion.

This is caused by the rotation of the Earth about It's North-South axis, which of course, is ~24hrs. Earth rotates toward the East at approximately 15 deg per hour. The same phenomena that makes it seem the sun (and stars) move across the sky almost 15 deg from East to West every hour.

Caused by the fact that the Earth orbits the sun on a yearly, ~365 day, trek. So if you observe the same stars on two occasions 10 days apart, the Earth will have moved in its orbit about the sun by almost (but not quite) 10 deg, affecting the aspect angle of you to the stars just slightly.
Also, the Earth's axis is tilted which can have an effect, but I won't go into that here...
I hope this helps.
