What Is Parallax A star has a parallax angle p of 0 723 arcseconds What is the distance of the star
There is an hinverse relation between star s parallax and its distance A star which has a parallax 1 arcseconds is at a distance of 1 parsec which is equal to 3 26 light years At such large distances the parallax shift becomes too small and we can no longer even see individual stars in galaxies Astronomers then turn to a series of methods that use quot standard

Cepheids Cepheids also called Cepheid Variables are stars which brigthen and dim periodically This behavior allows them to be used as cosmic yardsticks out to distances of a few tens of
