Earth revolve around the sun in anticlockwise direction and rotate about an its axis so the motion of earth is west to east with respect to star so according to the theorem of relativity we assume that star is moving east to west whenever the star is static with respect to earth and no one atmoshphere is moving.

Take an example of a person(A) in rest if there is another person(B) in a train, B will observe that A is moving in backward direction, however it is the train which is moving in forward direction, same will be the case of this question.

This is the principle of Frame of Reference.

We see stars because of the rotation of earth. The earth rotates from west to east. Consider a point just infront of your eyes in space, you keep seeing that point a turn your head from west to east the point will move from east to west. Same case with earth more accurate than this.

It's very simple thing.

I agree @Nikki.

Stars don't move in space. They are stationary.

While the earth rotates from west to east, it appears like stars moving from east to west (Nikki's example).

It is the same concept, the sun rising at the east and falling at west.

Its actually very simple to understand.

EARTH moves.

West ============> East.

West <=========== East.

STAR moves.

Its the same phenomenon which we have often experienced while traveling on any vehicle.

We feel like the trees are running in backward direction.

Retrograde motion is the apparent motion of a planet to move in a direction opposite to that of other bodies within its system, as observed from a particular vantage point. The stars rise in the east and set in the west as a result of the earth's rotation on its axis.

I think the best logic to choose an option is take earth as reference. they have told stars appears to move from east to west so any object which revolves around its own axis will make other objects around it to moce in its opposite direction.

It's very simple to understand if we are in the train we see trees and mountains can see like they are moving.

Which Means trains is moving but trees are stable.

So, this what I am saying is earth is moving but the star is stable li trees.

If you take a general situation where train moves in one direction but its surroundings seem to be moving in the opposite direction even though they are not.

The same perception can be seen in the direction of stars w.r.t to earth.

Sun is also a star and in general fact we say that sun rise from east and set from west but actually sun does not move it is stable. Due to revolution and rotation of earth from west to east it seems us moving like other star.
