How can parallax be used to determine the distance to nearby stars?

The reciprocal of the parallax is taken. For example, if the stellar parallax is 1 second, the distance is 1/1 = 1 parsec; if the parallax is 0.1 second, the distance is 1/0.1 = 10 parsecs, etc.

Then also Aline the thumb on a object in the background. Close the eye that dose not have thumb in front of it. Then close the other eye. Now put your thumb far away from you and close one of your eyes. Then do the same for the other. I hope this cleared up the confusion.

The distance to nearby stars can be measured by using?
Parallax
How do astronomers measure the distance to nearby stars?
Astronomers use a method called parallax to measure the distance to nearby stars. Astronomers can measure parallax by measuring the position of a nearby star with respect to the distant stars behind it. Then, they measure the same stars again six months later when the Earth is on the opposite side of its orbit.
Why must a star's parallax be known before you can find the luminosity?
What must be known is the distance. And the most accurate method to measure the distance of nearby stars is the parallax - but this method won't work for stars that are far away.
What is used to determine the distance to nearby stars?
They use trigonometry to determine the distance to nearby stars. They measure the star's positions at one point in time, and again six months later, calibrating against the backdrop of the far distant stars. The nearby stars will show a parallax shift in position, so they calculate a triangle, with the Earth at two points, and the base 186 million miles long. The star is the third point on the triangle, and it is simple trigonometry from there to figure out the distance.

Is parallax a star?
The parallax refers to the apparent change in the star's position, due to Earth's movement around the Sun. This parallax can be used to measure the distance to nearby stars (the closer the star, the larger will its parallax be).
