... 300 years ago it was discovered that stars move relative to each other and the constellations slowly change their shapes. The images to the left show Barnard's star, which has the largest proper motion of all stars. It moves by 10.4 arcseconds per year and its parallax amounts to 0.55 arcseconds. Ca ...
