The stellar parallax proves that the observer is moving.

Parallax gives the angular spacing between the two places of observation at the same time or the angular spacing of the displacement of the same location, for the two observations.

Stellar parallax is the apparent ( relative ) angular displacement of the star, due to the displacement of the observer.

The stellar parallax proves that the observer is moving.
