proper motion motion The projection onto the celestial sphere of the space motion of a star relative to the solar system; thus the transverse component of the space motion of a star with respect to the solar system. Proper motion is usually tabulated in star catalogs as changes in right ascension and declination per year or century.

reduced proper motion proper motion The observed proper motion of a star (in seconds of arc per year) reduced to absolute proper motion (in kilometers per second).
