Physics 1025: Lecture 17 Sun (cont.), Stellar Distances, Parallax
... How do astronomers pick out the nearby stars to measure? Answer: stars with large proper motions have large parallax (because they are nearby!) Think of people moving randomly in a park: those near to you will zoom across your field of view with large ‘proper motion’ (and being near to you will also ...
