Earth's Revolutions

Earth’s Revolutions

While Earth rotates on its axis, it also moves around the Sun in a path called an orbit. This motion is called revolution, and it takes about 365.25 days (one year) for Earth to complete one full trip around the Sun. Earth’s revolution, combined with the tilt of its axis, causes the changing seasons and...
