The earth's instantaneous velocity vector with respect to the center of mass of the solar system, needed for the precise reduction of annual aberration, is expanded into a trigonometric series using Bretagnon's (1982) planetary theory VSOP 82 for the heliocentric motion of the planets and Chapront-Touze's and Chapront's (1983) theory ELP 2000/82. The vector components are given in a rectangular coordinates system based on the fixed equator and equinox of FK 5 for the epoch 2000.0. The heliocentric motion of the earth-moon barycenter, the motion of the sun around the barycenter of the solar system, and the motion of the earth around the barycenter of the earth-moon system are discussed. The accuracy achieved by the development, estimated by comparison with DE 200, is better than 10 to the -7th AU/day, sufficient even for the most precise astrometrical reductions.
