Does our solar system move through the universe like a cloud moves through the sky or are we completely stationary?
Our solar system orbits the centre of the Milky Way galaxy.
Our galaxy, the Milky Way Galaxy, is rotating and our solar system lies in one of the spiral arms of the galaxy. The solar system is orbiting around the centre of the galaxy. It takes the solar system 225-250 million years to complete an orbit. This is sometimes referred to as a cosmic year.
