Compared to their distances from Earth, the space stars traverse is so minuscule that they appear immobile. Stars do move, though—the Sun, for example, has a space velocity of about 12 miles per second (20 km/s) in the direction of the star Vega.

This positional shift is called proper motion. For most stars, an appreciable difference can be discerned only after several thousand years. Some stars, however, have unusually large proper motions. Kapteyn's Star in the constellation of Pictor moves 8.9 arcseconds per year. In 200 years, it will have moved the wddth ot the Moon from its current position in the sky.
