Only supermoon of this year is this weekend

For those of us in the northern hemisphere, we are getting an extra-super supermoon because supermoons in the winter months look larger. Sunday's supermoon will be this year's only full-moon supermoon. That kind of full moon won't revisit Earth until 2034, according to NASA.

A supermoon only occurs when the full moon is the closest to the Earth, or at its perigree, and during this time, it can appear up to 14 percent larger and 30 percent brighter.

He says the moon's path around the Earth is oval-shaped, or elliptical. This is due to tidal and gravitational forces pulling the moon.

The only supermoon of 2017 is rising on December 3rd.

That puts the moon almost 26,000 miles (41,842 kilometres) closer to Earth on Sunday than usual. This changes though when we have a perigee or apogee.

There needs to be two factors for a supermoon to occur: a perigee which happens during a 27-day orbit and the full phase which is every 29.5 days.

The moon becomes totally full at 10:47 a.m. EST on Sunday, December 3.

As is the case with all celestial events, there are a few things you'll need to hope for if you want to catch this year's supermoon.

This optical illusion also occurs when watching the supermoon immediately after sunset (or before sunrise). Supermoon, also known as "cold moon" will appear in the skies of the United Kingdom.

Considering that a full moon can be covered with a fingernail, even a 7% larger moon may not look that much bigger.

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. When the moon rises over an object on the horizon the effect is most noticeable.

Many assume it's hard to differentiate between a supermoon and a regular full moon.
