Earth rotates once every 24 hours, at a speed of 1, 670 km/h (or 464 m/s). It makes one revolution around the Sun each year, at a speed of 107, 000 km/h, traveling 2.5 million km per day. The Sun, for its part, revolves around the galactic nucleus at 1 million km/h, taking 220 million years to make a complete revolution. Since it came into existence, the solar system has made only 20 revolutions of the Milky Way. | |
