Parallax Distance

Parallax is a displacement or difference in the apparent position of an object viewed along two different lines of sight, and is measured by the angle or semiangle of inclination between those two lines. It can be used to determine the distance to distant celestial objects by meausring differences at different points along Earth's orbit.

The distance is proportional to the reciprocal to the parallax angle.
