In astronomy, the term "barycenter" refers to the center of mass of a system of two or more bodies that are in orbit around each other. In a binary star system, for example, both stars orbit around their common barycenter, which is located at a point that is determined by the relative masses of the stars and their separation distance. The barycenter is important for understanding the dynamics of celestial systems.
