You use the stellar parallax method to determine the distance for stars less than 2,000 to 3,000 light-years away. ... One method is the famous Hertzsprung-Russel diagram, ...
Hurtling through interstellar space 4.3 billion miles from home, NASA’s New Horizons spacecraft has traveled so far that it has a unique perspective of the stars.
By comparing this to the view of these stars on Earth, astronomers will be able to view stellar parallax better than ever before. New Horizons was never designed to undertake this kind of study.
Parallax is the observed displacement of an object caused by the change of the observer's point of view. In astronomy, it is an irreplaceable tool for calculating distances of far away stars.
