The Moon's orbit around Earth is elliptical, with one side closer to Earth than the other. A "Super Moon" event occurs when the moon is a perigee. Perigee is the point in the orbit of the moon at which it is nearest to the earth.
The opposite of perigee is apogee, the point in the orbit of the moon at which it is the farthest away from earth.

On the average the distance between the moon and the earth is 238,000 miles (382,900 kilometers). At Perigee the distance is about 223,000 miles and the moon appears 13 per cent large and 30 per cent brighter. NASA estimates the distance on November 14 to be about 221,500 miles.
The Supermoon on November 14, 2016 is the closest a Full Moon has been to Earth since January 26, 1948. The next Super Moon event will be on November 25, 2034, and the Moon will appear even larger and brighter.
