Our solar system is not static; it is moving through space at an incredible speed. The entire solar system orbits the center of the Milky Way galaxy at an average speed of about 828,000 kilometers per hour (514,000 miles per hour). It takes approximately 225-250 million years to complete one orbit around the galaxy, a period known as a cosmic year or galactic year. This means that since the formation of the solar system about 4.6 billion years ago, it has completed around 20-25 orbits around the Milky Way.
