barycenterenUKbarycenter(ba -ră-sen-ter) The center of mass of a system of bodies, e.g. the Earth–Moon system or Solar System. The barycenter of the Solar System is offset from the Sun's center due to the presence of the planets, especially Jupiter, and moves as the relative positions of the planets change. Barycentric coordinates are a more rigorous coordinate system than heliocentric coordinates, specifying positions with respect to the Solar-System barycenter rather than the Sun's center.barycenter[′bar·ə‚sen·tər]barycenterenUK
