Motion
Sun and Solar System

The Milky Way is rotating around its dense Galactic Center, thus the Sun is moving in a circle within the galaxy 's gravity. Away from the central bulge, or outer rim, the typical stellar velocity is between 210 and 240 kilometres per second (470,000 and 540,000 mph). All planets and their moons move with the Sun. Thus, the Solar System is in motion.
