Is the Earth rotating around the center of the Milky Way?

Our sun and solar system move at about about 500,000 miles an hour (800,000 km/hr) in this huge orbit. So in 90 seconds, for example, we all move some 12,500 miles (20,000 km) in orbit around the galaxy’s center. Earth revolves (or orbits) around the sun. The sun revolves around the center of the Milky Way galaxy.
