Since the moon's orbit is elliptical (oval-shaped), its distance varies from about 221,463 miles (356,334 kilometers) at perigee (closest approach to Earth) to 251,968 miles (405,503 kilometers) at apogee (farthest point). The average distance from the moon to the Earth is 238,857 miles (384,392 kilometers).
Note: The actual Earth-Moon distance ranges from about 360,000 to 405, 000 kilometers, depending on the position in the Moon's orbit. To complete this activity you will need to download the Earth-Moon Distance image. The above image is linked to a larger one, so take the link to the larger image, then download.
