The change in the position of the star/planet is due to fact that the position of observation point has changed, in other words our line of sight has changed. The important thing to remember is that the change in the position of the planet/star is apparent and is with respect to a background fixed sky full of stars.
Try performing a simple experiment which demonstrates the parallax effect.
Keep your index finger in front of your eyes and by alternatively closing each eye observe the shift in its position with respect to the background (wall etc.)

Example -
When we hold a pencil in front of us against the background of a wall and look at the pencil first by our left eye A (closing the right eye) and then by our right eye B (closing the left eye), we find that position of pencil changes with respect to the background wall . This is called as Parallax.
Here AB = basis and angle AOB is called parallax angle.
So from the figure angle AOB = b/x where AB=b and AO=BO=x
This method can also be used to determine the distance to moon int he same way as done above.
