We had three in 2016, and the one on November 16 of that year was the closest we've had since 1948, according to NASA, and we won't have another one like that until 2034.

If you miss this one, however, don't fret: The first two full moons of 2018 will be supermoons.

According to Michelle Nichols, director of public observing at Chicago's Adler Planetarium, there is a reason behind the moon's captivating close approach to the Earth.

Traditionally known as the Cold Moon, this supermoon is a December-only phenomenon and will appear to be 14% bigger and 30% brighter than usual.

Perigee defines the closest point in the moon's orbit around the Earth, and the Supermoon will reach this spot at 3:45 a.m. EST on Monday, Dec. 4. December's perigee will bring the Moon within 221,821 miles to Earth.

A supermoon usually occurs when the moon is closest to the Earth in its orbit and this time sky gazers will see the moon at approximately 16,500 miles (26,500 km) closer than usual.

When the supermoon is viewed low on the horizon, it appears huge. Due to an effect called the Moon Illusion, it may appear bigger.

Wellington: In New Zealand's capital Wellington city, the full moon will be observed at 4:46 am local time on December 4.

What's the best way to photograph the supermoon?

FOX 13 Chief Meteorologist Paul Dellegatto says, because it's so close to Earth, a super full moon looks about 7 percent bigger and about 16 percent brighter than an average full moon.

To take a picture of the supermoon with a smartphone, tap on the moon on the screen and hold your finger in place to lock the camera's focus.

Do I need special glasses to watch the supermoon?

Then adjust the exposure slider that appears next to your finger to get the right balance of light for your shot. Especially if you get something in the foreground when taking photos.
