Does the Sun Move? What an interesting question. We mainly talk about everything in the solar system orbiting the Sun and celestial objects outside the solar system being in relation to the Sun. The answer to the question is : Yes. The Sun and the entire solar system orbits around the center of the Milky Way galaxy. The average velocity of the solar system is 828,000 km/hr. At that rate it will take about 230 million years to make one complete orbit around the galaxy.

Everything in the known universe rotates on an axis and orbits something else in space. The Sun is no exception. Here is the NASA webpage about the sun’s movements through space. Astronomy Cast offers two good episodes: one is about the mysteries of the solar system and the other is about solar system movements.
