The parallax can be used to measure the distance to the few stars which are close enough to the Sun to show a measurable parallax. The distance to the star is inversely proportional to the parallax. The distance to the star in parsecs is given by;

Parallax - Wikipedia, the free encyclopedia
Parallax is an apparent displacement or difference of orientation of an object viewed along two different lines of sight, and is measured by the angle or semi-angle of inclination between those two l...

In applications (notably astronomy) where parallax is used to measure the distance to a distant object, the parallactic shift is usually less than 1°. If q p is measured in seconds of arc, show that r is as follows: (Hint: how many second of arc are there in a degree?)

Units of Cosmic Distance: Light Year Parsec (Parallax second) ... Parallax decreases with Distance ... We saw before that the smaller the parallax, the larger the distance. We can express this as a simple formula: Where:

Determining distances through parallax ... In this picture we measure the parallax p, we know the size of 1 AU, so we can compute the distance d to the star. ... If the distance were twice as far, the parallax would be twice as small:

Parallax and Distances to the Stars ... The size of the shift -- the angle measured in degrees -- depends on how much you move your head and the distance between you and the window frame. Astronomers use this same concept to measure distances to stars.

If we use these units, the unit of distance is [648000/pi] au = 3.085678E18 cm = 1 parsec. A star with a parallax of 1 arc-second has a distance of 1 parsec. No known stars have parallaxes this big. Proxima Centauri has a parallax of 0.76". [The double quote is used to denote arc-seconds (as well as inches).]

This diagram is an overhead view showing the geometry of a parallax measurement. Such a measurement requires observations from two different places separated by a known distance.
