The Sun’s rotation around the solar system center of mass (barycenter) is the source of the solar magnetism subjected to the 11‐years cyclicity. The 11‐years cyclicity of the solar activity results from the solar magnetism produced by the Sun’s rotation around the solar system barycenter. The solar magnetism has two components: one of which results from its rotation about its proper axis, and the other –from its rotation about the barycenter of the solar system. Due to the solar system complexity the dimensions of trajectory loops created by the Sun’s rotation about its barycenter are constantly changing and once during several centuries the direction of the rotation changes, which may be associated with the existence of long durable cycles of the solar activity. The Sun’s rotation about the solar system barycenter it subject to calculations that might be used for forecasting the global climate for future years and even centuries.
