Catch the only supermoon of 2017 on Sunday

The full moon coming up on December 3 is the Cold Moon or the Moon Before Yule.

Due to the moon's extra-close approach to Earth, it will appear about 14 percent bigger than if it were at its farthest away point in its orbit.

The moon will be as close to us as it gets on Sunday as it makes its way around its elliptical orbit.

. That's when it was the smallest full moon for this year.

"If you stretch out your arm at full length, and stretch out your thumb, and compare the size of the full moon in the sky to the size of your thumb, you'll notice the width of the full moon compared to the size of your thumb; you can put four full moons across the width of your thumb". Additionally, some folktales note that if there is a snow storm during the Cold Full Moon, the snow will stop by the time the moon rises, which is good news for those who want to view the supermoon.

On the other hand, a micromoon occurs when a full moon or new moon coincides with apogee; the point in the moon's orbit farthest away from Earth.

The distance between the moon and Earth constantly changes.

However, December's full moon is the only visible supermoon.

What is a supermoon?

With the moon being as close to Earth as it is, there is a significant impact on the tides.

The supermoon on November 14, 2016 was at a distance of 221,526 miles.

According to National Geographic, the moon will appear seven percent bigger and 16 percent brighter during this year's supermoon.

Last year's supermoon saw the closest lunar approach in 69 years, but unfortunately the moon will not creep this close again until 2034.

For those using DSLR cameras, Ingalls recommends using another subject in the image, like a person, pet or landmark to compare to the size of the moon. Venus is very low on the horizon and about to disappear.

Unlike a solar eclipse, a supermoon can be viewed without any kind of eye protection, so you won't have to worry with getting special viewing glasses for this phenomenon. "Still, it's a great excuse to just go out and look at the sky", says Nichols.
