Stars appear to shift westward because of the Earth's daily rotation.
Also, there is a slower westward movement because of the annual motion of the Earth around the Sun.

What you get when stars are moving away?
When stars or galaxies are moving away from the observer, you will notice a redder shift in the color of the body.
Observation of the shift of a stars spectrum toward the red or blue enables us to determine the stars?
The star's velocity (away from us, or towards us).
What is actually moving when the stars appear to shift in the sky?
There not moving. One of your eyes is more dominant than the other so it appears to be moving when its really not
How does parallax shift varies with distance?
The closer the star, the greater the parallax angle, which is why you can't measure the distance to very distant stars using the parallax method.
Can there be purple shift aswell as blue shift and red shift?
Redshift and blueshift refer to a change in frequency of light we receive from distant objects (stars, galaxies, etc.) The light can turn different colors, and purple is one of them. However, no matter what the color the light changes to, the technical term is always "redshift" if the frequency of the light decreases (normally indicating that the object is moving away from us), and "blueshift" if it increases (normally indicating that the object is moving towards us). Blue shift and purple shift would mean the same thing because the spectrum is one-dimensional. It's like if you are in Boston, a shift towards Chicago is the same as a shift towards San Francisco. Obviously, a purple shift is a super blue shift.
What factors were responsible for westward shift of trade?
Please be more specific westward shift of what trade?
Why do the the patterns of the stars appear to shift westward slightly from night to night?
This shift in the constellation is due to two effects. #1 The Earth's axial (daily) rotation & #2 The Earth's orbital track about the Sun.
What cause Earth's precession?
A slow westward shift of the equinoxes.
What is the aparent westward movement of stars called?
retrograde motion
The apparent westward movement of a planet against the background of stars is called?
"Parallax shift". We can't SEE the difference in position of any star as seen from the Earth 6 months later or earlier, but by measuring the very tiny differences in the positions of the more distant stars, we can observe the "parallax" of a star and thus calculate its distance. This only works for stars less than about 300 light years from Earth.
How did the American western frontier shift westward?
By the promise of free land and the Doctrine of Manifest Destiny.
Why do the stars appear to move slowly westward at night?
The earth is constantly moving eastward, so the stars appear to move westward. This is an optical illusion that is supported by Newton's 3rd Law (every action has an equal and opposite reaction).
What is a stars shift in position called?
Motion
