Basic Observations of Stars
... The apparent distribution of stars as seen on the sky can be monitored and the ‘sideways’ motions measured as changing directions, expressed as angles. This is called the star’s proper motion. (To calculate the actual speeds through space, we need to know their distances as well.) The changes are mo ...
