a crazy carnival attraction

Like a crazy carnival attraction, Earth is spinning, circling, and racing through space. It rotates on its axis once every 24 hours and orbits the Sun at a speed of 65,000 mph. Earth and the rest of the solar system orbit the center of the Milky Way galaxy at 600,000 mph, so it takes about 200 million years to complete one circuit.
