Moon Transiting the Earth – EPIC View

An “EPIC” animation of the Moon transiting the Earth created with actual satellite images of the far side of the moon, illuminated by the Sun.

While the moon was crossing between the DSCOVR and the Earth, EPIC took these beautiful photos almost one million miles from Earth.

The distance between the Moon and Earth varies from around 356,400 km to 406,700 km at the extreme perigees (closest) and apogees (farthest).
