WebTypical values for the space velocities of stars are 20-100 km/s. To measure proper motion, astronomers typically compare images of the sky taken 20-50 years apart and note how much a given star has moved relative to distant background objects (usually galaxies or quasars). Typical proper motion is around 0.1 arcsecond/year.
