Lunar Orbit - This animation demonstrates the Moon's orbit around Earth. Earth and the moon are shown at their true relative sizes but the moon is placed about 5 times closer to Earth than its actual distance. Earth's rotation has been slowed for aesthetic purposes. In realisty, Earth rotates about 29.5 times in the time it takes the moon or orbit one time with respect to the sun (the cycle of phases).
