Parallax is the phenomenon in which the apparent position of a celestial object on the celestial sphere shifts angularly relative to much more distant background objects due to a change in the observer’s position in space. This shift arises not from any physical movement of the object in space but from a change in the observer’s line of sight. The parallax method relies on measuring this angular change, which is evaluated geometrically and mathematically from observational data. Parallax is defi
