No, only the closer ones have a parallax that is large enough to be measured. The first star to have its parallax measured was 61 Cygni, measured by Bessel in 1838 and found to be at a distance of 10.3 light years, later corrected to 11.4. The closest star Proxima Centauri has a parallax of only about 0.7 seconds of arc. Before then the absence of parallax for the stars was considered an important part…
The star 61 Cygni had its distance measured by Friedrich Bessel in 1838. He found a distance of 10.3 light years, close to the modern value of 11.4 light years. This was the first time a star's distance was measured. The method used was to measure the star's parallax, the slight movement seen against the background of more distant stars caused by the Earth's motion around the Sun.
